Gwyneth Paltrow supposedly hates the motherloving crap out of Scarlett Johansson, who is playing the role of the Black Widow in Iron Man 2. Oh MAN do I love a good catfight. This might be the best thing that ever happened to me. Well, today, anyway. Then again, that burrito I had for lunch was pretty good.

One Hollywood source revealed yesterday: “Gwyneth has become very frustrated with Scarlett. “They come from different worlds and have completely different styles. “Gwyneth has found Scarlett very demanding of the attention of the crew. It’s not a happy set.”

“Gwyneth was looking forward to working with EMILY BLUNT, who was originally in line for the part, but it ended up being Scarlett. Gwyneth’s had to live with that and she has been very professional, but she and Scarlett haven’t developed a friendship on the shoot, which is almost at the half way point. “In fact, it’s quite the opposite.”

While Scarlett has been donning sexy catsuits and carrying guns for the scenes shot so far, Gwyneth has mainly had to settle for prim business suits. (Source)

I can already picture the headline to the next GOOP newsletter. "How To Passive-Aggressively Be Condescending to Your Younger More Attractive Costar Who Thinks She's So Great Because She Gets To Wear Sexy Clothes and Woody Allen Loves Her and Her Husband Probably Still Has Sex With Her That Bitch." Also in the next GOOP? The best spots for the perfect manicure in SoHo.
