Pink Parties Hard With Ex-Husband Carey Hart

Outspoken pop star Pink spent New Years partying hard in the company of her ex-husband Carey Hart in Las Vegas.

The couple - who officially split in February 2008 - seem to be on good terms after the So What star rang in 2009 at one of Carey's hotels.

A source tells People, "They didn't really talk much, but at midnight Carey grabbed her and took her up to the stage and introduced her.

"Then he wished everyone a happy new year. It was very informal."

Pink later put in a performance at Hard Rock Hotel's Wasted Space.

There was no romantic renunion for the pair but in Hollywood anything can happen!
