was in the awkward position of shooting a sex scene with her Titantic
lover Leonardo DiCaprio
in the upcoming film Revolutionary Road
- directed by her husband, Sam Mendes
'I just kept saying, 'This is too... weird,'' the actress, 32, 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.'"
But Winslet was pleasantly surprised by the result.
'I hadn't realized 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."
For his part, Mendes - her husband since 2003 - told the magazine: 'I will admit it was quite bizarre to direct my wife in how to make love. But it's difficult whether you're married to a person or not.'
Winslet and DiCaprio, 33 - who starred in Titanic
in 1997 - play a suburban couple in the film, based on Richard Yates' 1961 novel.
'We knew that if we were going to do something again, it had to be something big and emotional,' Winslet said of reuniting with DiCaprio, which she arranged. 'I played this very clever cat-and-mouse game to get my husband and then my best friend involved.'
