Justin Timberlake Offers Support to Britney Spears

Justin Timberlake is among the stars who have been quietly reaching out to show their support to Britney Spears as the pop singer battles substance abuse in rehab.

Friends claim Timberlake left a personal message for his ex-girlfriend after calling the Promises treatment centre in Malibu, Calif., last week.

A pal tells Life and Style magazine, "He wished her the best and told her to get healthy and come back as the Britney he knew."

Timberlake has asked Britney Spears mother Lynn to keep him updated with the singer's progress.

Pink and Mary J. Blige have also called Promises to leave messages for Spears, who, under the center's rules, isn't allowed to receive phone calls during her stay.
