Sandra Bullock and Jesse James

When Kate Winslet won Best Actress in 2009 for The Reader, Winslet thanked her "wonderful husband and two beautiful children who let me do what I love and who love me just the way that I am."

Charlize Theron and Stuart Townsend

• From Oscar to Split: 6 years

As Charlize Theron accepted her Oscar for Monster in 2004, she thanked her longtime love Stuart Townsend: "I have to thank my incredible partner in crime. You are one hell of a partner to have. Thank you for standing by me." The couple ended their nine-year relationship in January 2010.

Halle Berry and Eric Benet

• From Oscar to Split: 7 months

In 2002, Halle Berry took home the Best Actress Oscar for Monster's Ball. The gorgeous actress star stood by her man when he went to rehab for sex addiction. But seven months later, Halle announced her separation from her husband of three years.
