Love wasn't better the second time around (or maybe third, or fourth -- honestly, we kinda lost track) for Jude Law and Sienna Miller. Originally engaged on Christmas in 2004, they split in 2006 after the actor's dalliance with his kids' nanny. They reunited in 2009 before calling it quits, supposedly for good, in February 2011. Among the reasons given for the bust-up: Sienna found the former Sexiest Man Alive "really rather boring." She reportedly rebounded with another British actor, Tom Sturridge.
