Gwyneth has a different version of events:"It was great because both my husband Coldplay's Chris Martin and his wife Iron Man 2 executive producer Susan Downey were right there."

"She said to me that I didn't know what I was doing, like it didn't feel good," he said. "I'm like, you know what? First of all, we're all friends, so what would be creepy would be if I was coming off all sexy to you — which by the way, I've done that in movies and it creeps them out. So what am I going to creep you out for?"

Mom-of-two Gwyneth laughed him off, but Robert, who plays businessman Tony Stark, added: "Despite what she said on set, she still thinks about it."
