Los Angeles- If Britney Spears didn’t already have her hands full , she certainly does now.

A raunchy sex tape starring the pop singer was leaked on the web today. The 30 minute video shows the shaven headed pop star performing sex acts with 2 unidentified females and a male companion. During the video , the dazed britney consumes alcohol and what appears to be cocaine and marijuana.

The tape will undoubtedly cause more problems for her already troubled custody battle with ex-hubby Kevin Federline

Spears had to temporarily surrender custody of her sons to Federline because she defied a court order.

After-hour calls to attorneys representing Spears and Federline were not immediately returned.
