Pop star Britney Spears has voluntarily checked into rehab following her DUI arrest in Ventura County in March, a representative for the singer told CBS LA.

Britney Spears showed off her dance moves in a sheer black thong bodysuit just hours before she checked herself into rehab.

Britney Spears' ex Kevin Federline—with whom she shares sons Sean Preston, 20, and Jayden James, 19—is "happy that she is getting help" after checking into a treatment facility, his lawyer said.
