As LeAnn Rimes turns 27 today, look back at other stars who have come between couples
Claire Danes and Billy Crudup
The former My So-Called Life star met the Almost Famous rocker on the set of Stage Beauty in 2003, which prompted him to leave his girlfriend of nearly eight years, Mary-Louise Parker, who was seven months pregnant with their son. Although Danes and Crudup were together for four years, she reportedly began an affair with her now-fiance Hugh Dancy while they were still dating.
