Gwyneth Paltrow sexually charged by Robert Downey Jr

London, May 08 : American actress Gwyneth Paltrow has revealed that she felt "sexually charged", while doing her scenes with her Iron Man co-star Robert Downey Jr.

The 35-year-old actress had recently spiced up her looks with killer heels and low-cut tops, and she revealed that she enjoyed the on-screen chemistry that went on with Downey Jr.

"Robert kept me on my toes and kept our onscreen relationship sexually charged," The Sun quoted her as saying.

"Sometimes I have had to work with people I have had zero chemistry with and it's like pulling teeth.

"Because sometimes it's just not there and when it is there, it's like flying. It feels like you can do anything, and when it's not there it's a struggle. I've had that quite a few times," she added.

Paltrow has secured a number of quirky indie films like 'Running With Scissors', and has said that she jumped at the chance to star in a blockbuster, though she would like to do something more.
