8 Least Likely Celeb Homewreckers

Susan Sarandon's 23-year relationship with Tim Robbins may have been broken up by her affair with a much younger ping-pong player…or it may have been broken up by Meg Ryan. Yes, that Meg Ryan: "America's sweetheart." But she's not the only unlikely celebrity homewrecker. The Frisky found seven more:

• Alicia Keys: The seemingly sweet singer who found fame as a teen allegedly broke up fellow singer Mashonda's marriage to Swizz Beatz.

• Natalie Portman: Another adorable former child star, who—maybe—messed around with Sean Penn before he split from wife Robin Wright.
• Claire Danes: Sweet little Angela Chase came between Billy Crudup and seven-months-pregnant Mary-Louise Parker.
