But behind the scenes the Just Like A Pill star, 29, and motocross racer Hart, 33, had not actually divorced, and insisted they remained close friends.
The two married in Costa Rica in January 2007 after an on/off six year relationship.
The couple announced they were separating in 2008, but again, the split didn't last for long: They were back together in early 2009.

'We're definitely putting in work on our relationship.'Pink and Hart met in 2001 at the X Games and dated for two years before breaking up in 2003.
