Hindsight: (Noun) Understanding of a situation or event only after it has happened.

Everyone's favorite adulterous couple, Sienna Miller and Balthazar Getty, have called it quits. Aww, how sad. Following rumors when she was seen out partying by herself in London recently; Sienna herself confirmed it during an all-nighter Friday night.

Sienna's first stop was the star-studded Hollywood Dominoes: VIP launch event at Mosimann's where she confirmed the split to American magazine Us Weekly. She told the magazine: 'I'm single at the moment, and I'm completely happy with that. 'It's nice not to have a relationship that the press constantly want to scrutinize and discuss. 'I'm cool with being on my own.' (Source)

Balthazar Getty, however, could not be reached for comment as he is no doubt groveling at the feet of his estranged wife and mother of his four children. What kind of gift best says, "I'm sorry I left you for four months to go run off with some whore and let the press take pictures of me groping her nekkid boobies?" Diamond jewelry or a new house? Hell, I'm thinking a house -- wait for it -- made out of diamonds.
