Actor John Travolta has said he isn’t worried about Robin Williams filming sex scenes with his wife Kelly Preston.

The 55-year-old star said he found it hard to watch his wife’s sexy scenes with actors such as Tom Cruise in movie Jerry Maguire and Kevin Costner in Love Of The Game.

Travolta has been married to Preston, 47, for 18 years and she stars in new film Old Dogs with Williams, 58.

He said: “I have been jealous of many of her co-stars. I didn’t like her making love to Tom Cruise.”

Travolta added: “I didn’t like her making love to Kevin Costner in Love Of The Game. It was hard to watch.

“All I can say is thank God for Robin. I adore Robin so it was OK with him.”
