top Former Broadway star Craig Bierko dated Theron for two years before moving on to comedienne Janeane Garofalo.

Not long after, Bierko got cosy with Meg Ryan who was nursing a broken heart from her split with Russell Crowe and her divorce from Dennis Quaid.

As luck would have it, Bierko's biggest role to date was opposite Crowe in Cinderella Man, where there was said to be no love lost between the two actors due to their common ex-girlfriend.

He has been dating singer Vanessa Carlton (he produced her last album) for more than two years.

top Kelly Preston has been married to John Travolta for 14 years-a lifetime in Hollywood terms.

Prior to Travolta, Preston was married to her Space Camp co-star Kevin Gage.

Theron and long-time love Stuart Townsend have been an item since meeting on the set of the thriller Trapped.

Theron said recently that she foresees she and Townsend being like Goldie Hawn and Kurt Russell-together for years but not married.

Townsend is not as A-list as his girl, however he might have been had he played Aragorn in The Lord of the Rings trilogy as he was set to do.

Viggo Mortensen replaced the Irish-born actor after only four days of filming reportedly because he looked too young for the role.

top George Clooney continues to be Hollywood's most eligible bachelor.

The Syriana star has been serious with his share of beauties including actresses Kelly Preston and Rene Zellweger, but since a short-lived marriage early in his career, no one has gotten him close to the altar.

Recently Clooney ended his five-year on-again, off-again relationship with British TV presenter Lisa Snowdon.

Last month the star was spotted with Italian heiress Gianna Cantalone and was on the receiving end of some heavy flirting by Teri Hatcher at the premiere of his film Good Night, and Good Luck.
