Gwyneth Paltrow is reportedly furious Scarlett Johansson is featured in Iron Man 2’s new promo pictures as Black Widow and she isn’t.  Now Gwyneth is supposedly boycotting Comic-con.

Madonna, Reese Witherspoon and Gwyneth Paltrow are Hollywood’s top money-making mamas.

First, Gwyneth Paltrow was rumored to be putting co-star Scarlett Johansson on a strict workout plan.

Now, the actress turned fitness guru is apparently looking to help her pal, chef Mario Batali, shed a few pounds, too.

Gwynnie has offered the hefty chef a free membership to her ultra swanky TriBeca gym that opens this summer, the New York Post report. Paltrow started the health club — which has a whopping $4500 sign-up fee, not including monthly payments — with her friend and trainer, Tracy Anderson.

A source tells the paper,”Mario is the only fat friend she has, and wants him to change.”

Sounds like the queen of GOOP has a brand-new project.

Gwyneth Paltrow attempts to get “real” and doles out some advice for anyone who has a mean girl on her hands.

“Back in the day, I had a ‘frenemy’ who, as it turned out, was pretty hell-bent on taking me down,” she professes her latest GOOP newsletter.

“This person really did what they could to hurt me. I was deeply upset, I was angry, I was all of those things you feel when you find out that someone you thought you liked was venomous and dangerous.

“I restrained myself from fighting back. I tried to take the high road.” (Of course you did, Gwynnie.)

“But one day I heard that something unfortunate and humiliating had happened to this person. And my reaction was deep relief and…happiness.”

Hmmm…sounds like Paltrow may  be talking about her former BFF Winona Ryder, who was arrested for shoplifting back in ‘01.

The two were attached at the hip until Gwyneth reportedly stole her Oscar-winning Shakespeare in Love role from Winona.

Gwyneth rides along on her high horse, saying, “So, why does it feel so good to hear something bad about someone you don’t like? Or someone you DO like? Or someone you don’t KNOW?”

And of course, no GOOP letter would be complete without some inspiring words from Ms. Paltrow, who ends her post:

“Here’s to washing our mouth’s out with soap.” Indeed.

Scarlett Johansson is busy sculpting herself into what she calls “superhero shape” for her upcoming film, Iron Man 2.

In the process, the bombshell has stirred up rumors that her co-star and workout die-hard Gwyneth Paltrow has had a little something to do with her new slimmer figure.

Now Scarlett, 24, is firing back at the reports, saying she’s just prepping for her role.

“Claims have been made that I’ve been on a strict workout routine regulated by co-stars, whipped into shape by trainers I’ve never met, eating sprouted grains I can’t pronounce and ultimately losing 14 pounds off my 5′3″ frame,” ScarJo blogs in the Huffington Post.

“Losing 14 pounds out of necessity in order to live a healthier life is a huge victory. I’m a petite person to begin with, so the idea of my losing this amount of weight is utter lunacy.”

Um, “utter lunacy”? Even if she’s not getting dieting tips from Gwynnie, Scarlett seems to be picking up on her co-star’s fake British vocab.

Adds Johansson: “If I were to lose 14 pounds, I’d have to part with both arms. And a foot. I’m frustrated with the irresponsibility of tabloid media who sell the public ideas about what we should look like and how we should get there.”

Iron Man 2 hits theaters in May of 2010.

‘Tis the season for some spring cleaning, and for Gwyneth Paltrow, that means cleaning out the ‘ol closet.

Gwynnie took to her GOOP newsletter to let her fans in on a little secret — a few select items from her closet have made their way to eBay.

Proceeds from the sale will go towards the Robin Hood Foundation which targets joblessness, teen pregnancy, abuse and AIDS in New York City.

“I recently did a good look-through and found some things that I will now call ‘vintage’ as well as doing a big cathartic spring cleanout. I thought maybe I would eBay some of my favorite and most treasured things to raise some money for the Robin Hood Foundation, who do a lot of amazing work in New York City,” Gwyneth wrote.

Up for grabs? Loads of designer goods, including Jimmy Choo and Valentino bags, Burberry sandals and a Balenciaga cocktail dress.

And it wouldn’t be a GOOP newsletter if Gwyneth didn’t offer up her two cents of advice.

The Oscar-winning actress turned recent designer suggests sticking with nautical and ethnic prints, trench coats, and jumpsuits this spring.

Paltrow has just begun filming Iron Man 2 which hits theaters in May of next year.

Scarlett Johansson loses a few of her famous curves after her Iron Man 2 co-star Gwyneth Paltrow turns her on to a new fitness routine. (Guys, now you know who to blame.)

Gwyneth Paltrow is the latest celeb to turn fashion designer.

The 36-year-old is teaming up with French label ZOEtees’s and is collaborating on a new collection for the brand, ZoeTee’s Loves Gwyneth, Elle UK reports.

The line, set to launch for Autumn/Winter ‘09, will include ’70s-inspired pieces, with masculine tailoring.

Proceeds from the sale of ZoeTee’s Loves Gwyneth will go to Gwynnie’s favorite charity–London’s Kids Company.
