After being criticized in the past for being too skinny, a curvier Megan Fox has been spotted on the set of her new movie and has spoken out about her weight gain.

Megan Fox may be losing her Marilyn Monroe tattoo, but she says she’s been trying to gain weight. The actress was spotted in brown leather shorts and a black tank top on the set of her new movie This is Forty looking curvier than she had in the past.

Megan Fox weight gain

“People thought, ‘Oh she must be anorexic,’ but she’s far from that,” her trainer Harley Pasternak said. “Believe it or not she has this really fast metabolism, so her training is all about body toning and sculpting. With her it’s really about whether she’s eating enough of the right things.”

In fact, he said she “gets frustrated at times” because she needs to put on weight.

The Jennifer’s Body actress recently told the Italian magazine Amica that she put on weight after she quit her strict vegan diet.

“For a year and a half, until about four months ago, I followed a strict vegan diet based on raw fruits and vegetables, no bread, sugar and coffee,” she said. “But I had lost too much weight. So now I eat a bit of everything. I train three times a week doing circuit training with my trainer Harvey Pasternak.”

Fox also confessed to Fox News she didn’t have the healthiest diet.

“I just stopped eating,” Fox said. “I don’t eat very healthy anyway — I have a serious sugar tooth, so now I eat red-velvet cake before I go to bed every night, and if you eat meals later, you’ll put on weight faster, so I had dinner at 10 p.m.”

The 25-year-old actress revealed she also had to put on weight back in 2008 for Transformers director Michael Bay. “I’d lost a lot of weight and got really scrawny but I was told I had to put on a size for Transformers because Michael doesn’t like skinny girls.”

Gentlemen may prefer blondes — but Megan Fox would now prefer to have her giant Marilyn Monroe tattoo erased from her right forearm.

The 25-year-old star confirmed to Italian fashion magazine Amica that she is in the process of removing (via laser treatments) the talked-about portrait of the Hollywood legend from her famous body.

“I’m removing it,” Fox says. “She was a negative person, she was disturbed, bipolar. I do not want to attract this kind of negative energy in my life.” (Indeed, the notoriously troubled Monroe died in 1962 at age 36 of a drug overdose.)

But the Transformers bombshell has plenty of other body art staying on — with over nine other tattoos, including a quote in honor of her Passion Play costar Mickey Rourke on her ribcage, a tribal tattoo on her left wrist and another quote on her shoulder.

“Who knows, maybe I’ll remove the others too, but the laser hurts.”

Fox also fesses up to removing, like so many young women before her, a naval piercing.

“I did it when I was 16-years-old because I was a fan of Britney Spears,” she explains. “The only time I tried to imitate someone else. But then I thought it was tacky and so I removed it when I turned 20.”

Megan Fox is diving headfirst into her role in the upcoming comedy This Is Forty.

The 25-year-old actress shared a behind-the-scenes photo with costars Chris O’Dowd, 31, and Jason Segel, 31, on Facebook Saturday, calling them “two very handsome, very tall, very funny men.”

Though Fox showed off her healthier new curves on Wednesday, she kept her figure hidden while posing underwater in the pool.

The Judd Apatow flick, which revolves around Paul Rudd and Leslie Mann’s characters from the 2007 smash Knocked Up, also stars Melissa McCarthy, John Lithgow, Maude Apatow and Ava Sambora.

“Megan is hilarious,” Rudd, 42, recently told E! News. “I don’t know if people don’t realize that, but she is really really funny.”

Who wants to see Megan Fox all Knocked Up?

Well, now you can.

No, she’s not pregnant, but…

Fox was spotted earlier this week in Los Angeles filming This Is Forty, Judd Apatow’s Knocked Up sequel that revolves around Paul Rudd and Leslie Mann’s characters from the hit comedy.

Fox has a costarring role, but details about her character remain a mystery. During the outdoor shoot, she looked healthy and not as thin as she has been in the past. She wore what looked like brown leather lace-up shorts, a simple black tank top and brown leather and zipper heels.

“Megan is hilarious,” Rudd told me last night at the Nylon Guys and WeSC party at Gjelina restaurant in Venice. “I don’t know if people don’t realize that, but she is really really funny.”

Fox’s comedic chops aside, I’d be remiss not to tell you what Rudd had to say when I asked him about wearing a long hair wig for his latest movie, Our Idiot Brother (out Aug. 26).

“I used to have long hair when I was 18 until about 22,” he said. “It wasn’t a hippie thing. I was hoping to look like Michael Hutchence from INXS. I pretty much didn’t cut my hair for four years.”

Almost everyone can agree that Megan Fox has been going through a rough patch recently. Whether she’s being accused of having excessive plastic surgery done or being fired for comparing her boss to Hitler, this actress quickly transgressed from being the next big thing, to the next big flop. Sure, she hasn’t lost a lot of her dedicated male fans because they still worship her as an incredible sex symbol, but she is a far cry from role model material and has a dwindling acting career. Apparently, all of that is about to change for this Foxy lady. In a recent interview for the September issue of Amica Magazine, the actress claims to revamping her career and starting fresh — which includes making some changes in her life.

As part of her new career attempt, Fox is deciding to take smaller parts in smaller movies and trying to find her niche in the comedy/rom-com/drama family. It may be hard to picture the seduction queen busting out jokes, but she seems to be making strides into the humorous realm by rubbing elbows with the likes of Jason Segel and Paul Rudd in an upcoming film titled This Is Forty. Who knows, she may turn out to be a comic genius and surprise us all. Along with this new and improved Megan, she’s also deciding to ditch some of her body art that has graced her stunning figure. In regards to her Marilyn Monroe tattoo, Fox tells the magazine that “I’m removing it. It is a negative character, as she suffered from personality disorders and was bipolar. I do not want to attract this kind of negative energy in my life.” So, in the words of Elton John — goodbye Norma Jean.

The actress also seems to be looking a lot healthier these days and has reportedly gained 10 pounds, which looks great on her. While on her strict vegan diet, she appeared to look a little skeletal, but now that she’s back to eating more like a normal human she’s filled out and is back to looking gorgeous.

We don’t know too much about Judd Apatow’s “Knocked Up” spin-off movie project, other than the fact that it centers around lovable/slightly dysfunctional couple Pete (Paul Rudd) and Debbie (Leslie Mann), a few years after the events that occur in the Katherine Heigl, Seth Rogen pregnancy comedy. Also, if we know one thing about Apatow comedies, it is more than likely that a slew of famous faces will appear in the film, be it in a supporting or cameo role.
Apatow has been cagey about revealing any more casting or cameo details, but one interesting addition that was actually announced back in March is Megan Fox, and although we don’t yet know who she plays in the film, star Leslie Mann assured us that she is a welcome addition to the cast.

“Megan Fox is so funny,” she told us Monday night at the Los Angeles premiere of “The Change-Up.” “She’s hilarious. You wouldn’t, I don’t know if other people [expect it], but I think she’s really funny, you’ll be pleasantly surprised.”

So who does she play in the film?

“I can’t say that part,” she said with a smile, backing up her husband’s comments earlier this year regarding spoilers.

“The rest is a secret because it doesn’t come out until 2012 and if you already knew what it was about for a year and a half, you wouldn’t even want to see it,” he told us. “There will be people who are really interesting in the movie,” he teased. “And some familiar people who are in the movie.”
