Cate Blanchett slept with her Best Actress Oscar. The 'Blue Jasmine' actress - who also won Best Supporting Actress in 2004 for her role in 'The Aviator' - joked she and husband Andrew Upton had had a "threesome" following the Academy Awards on Sunday because she couldn't bear to let the statuette out of her sight. She said: "It's the closest my husband and I have ever come to a threesome." The actress admitted accepting the award was a bizarre experience. She explained: "I was so stressed. I don't think I drank that much last night but it was such a release of adrenaline." Cate appeared on Ellen DeGeneres' talk show just hours after the ceremony and admitted to the host - who had presented the awards - that she had only had "a little bit of sleep". Ellen said: "What can I get you? I have Visine, I have Advil. I have water. I have a banana." The actress replied: "Do you have a blanket or a coffee or something?"
