The two starring women appeared to be suffering from metal fatigue during the Iron Man 2 premiere.

Scarlett Johansson and Gwyneth Paltrow attended the Iron Man 2 premiere in Los Angeles, but they did not pose for photos together on the red carpet!

It just added fuel to the rumours that the two didn’t get along throughout filming.

Gwyneth didn’t enjoy Scarlett’s “attention seeking” behavior during filming, according to the tabloids. She was even more irritated when her younger co-star appeared on the movie’s poster in a skin-tight cat costume… and Gwyn was left out.

While Scarlett has played down rumors of a dispute, Gwyneth has been silent on the subject.

Her representative was quick to note out that she was “not at all upset” about her absence from the film posters, but she passed up the chance to deny a rift.

Scarlett said of the film, which also stars Samuel L Jackson and Robert Downey Jr., “I was so lucky because I had Gwyneth to counterbalance all that testosterone. It certainly was a bit of a boys’ club.

“Luckily I am entertained by all of that. I think that for the guys this movie was their playground, they had all of the big toys and all of the big action sequences.

“Luckily, I exuded enough femininity to kind of quieten them down a little bit.”

Gwyneth and Scarlett both wore white for the evening.

Whatever the reality is behind the squabbles, Scarlett was the winner of the style battle that night.
