Justin: 'I called Britney in rehab'

Justin Timberlake was so worried about Britney Spears when she entered a rehabilitation clinic earlier this year that he called her.

Although the former childhood sweethearts split up over five years ago, Timberlake was concerned when his ex-girlfriend checked into the Promises Centre in Malibu in February.

Spears checked out of the clinic on March 20 and Timberlake insists that she is now on the mend.

Timberlake said of Spears: "I called her because I worried about her. She's a great woman. I'm rooting for her. It seems like she's getting everything under control now."
