Kate Winslet has apparently revealed she felt a little odd filming a sex scene with Titanic co-star Leonardo DiCaprio on their new movie Revolutionary Road, which was directed by her husband Sam Mendes.

"I just kept saying, 'This is too... weird,'" the 32-year-old British
actress told Entertainment Weekly. "And Leo was like, 'Oh, get over it.' And I'm going, 'Yeah, a little reminder: You're my best friend. He's my husband. This is a bit weird.'"

However, Kate has revealed that they were able to revive the old Titanic chemistry in the new movie about a 1950s American couple.

"I hadn't realised how much my chemistry with him since Titanic would still stick," she said. "It's great to discover we can just slip right into it, like muscle memory.

"We knew that if we were going to do something again, it had to be something big and emotional," she added. "I played this very clever cat-and-mouse game to get my husband and then my best friend involved."
