Britney Spears and Kevin Federline are facing marital problems after the pop diva found out about a dubious liaison between her husband and French actress Sandy Lakdar.

Britney was holidaying in Maui, Hawaii on February 22, when a friend called to inform her about Kevin's infidelity. The pop star got really furious when she heard about her husband's photos picturing him in the arms of another woman.

Federline, who was working on his debut album in Los Angeles, was caught on camera getting cozy with a sexy young French woman, called Sandy Lakdar, outside Hollywood's Millennium Studios.

A friend of Spears relates: "She was literally kicking and screaming (when she heard about the photos). When she got back to her suite, she was so furious, she destroyed everything in sight. She called Kevin but couldn't reach him."

The same friend says the pop star was so angry that she immediately ordered her husband to pack his bags and "get the hell out" of their house in Malibu, California. But the 25-year-old French actress is trying to defend Federline, saying that she first met him the day the photos were taken. And besides, Britney has no reason to feel threatened by her, as she already said: "I do not fuck married men".
