Robert Downey Jr may be a Hollywood heartthrob but actress Gwyneth Paltrow was apparently not too keen to lock lips with him in Iron Man 2.

He may be a Hollywood heartthrob but actress Gwyneth Paltrow was apparently not too keen to lock lips with Robert Downey Jr in Iron Man 2.

Downey, who plays the role of a playboy superhero Tony Stark in the film admits that Paltrow found him lacking in the love department, People reported online.

"She said... I didn't know what I was doing, like, 'It didn't feel good. And I said, 'You know what? First of all, we're all friends, so what would be creepy is if I was coming off all sexy to you while we were shooting – which by the way, I've done that in movies and it creeps them out! So why would I creep you out?'," Downey said.

However, the 45-year-old star enjoyed the moment despite Paltrow's protests."She still thinks about it, I couldn't get her off me!," Downey said.

One of the reasons for her discomfort owes to the fact that present during the scene were both her husband, 'Coldplay' singer Chris Martin, and Downey's wife, producer Susan Downey.

"It was great, because both my husband and his wife were right there on the set," Paltrow said.
