The male model who briefly dated Britney Spears earlier this year has sent the troubled singer his best wishes during her current stint in rehab.

Spears, 25, checked into Promises Residential Treatment Center in Malibu, California on 21 February, following months of incessant partying.

Isaac Cohen, who dated Spears for a month earlier this year, admits he was surprised to hear of the extent of her problems, because she didn’t seem that out of control when they were together.

American designer Marc Jacobs has checked into rehab after a recent relapse.

The 38-year-old decided to enter a rehab centre in Arizona after showing his Louis Vuitton collection during Paris Fashion Week last week.

Jacobs has been sober for seven years, but decided to seek treatment after his relapse. He previously entered rehab in 1999.

Singer/actress Mandy Moore and Adam ‘DJ AM’ Goldstein ‘amicably’ ended their relationship earlier this month, according to reports.

A source tells American publication People the end of the two-month relationship “was mutual.”

Moore, 22, and Goldstein, 33, have known each other for years, and began dating after running into each other at a New Year’s Eve party in Miami, Florida.

The pair were spotted at the Sundance Film Festival in January.
