Spears, 25, arrived at the Van Nuys Community Police Station at 9 p.m. (midnight ET) Monday, said Los Angeles Police Department spokesman Mike Lopez.

TOULOUSE, France (AP) -- French rock star Bertrand Cantat, convicted for beating his actress girlfriend to death, left prison Tuesday after spending four years behind bars.

After holding talks with the president, Tymoshenko and the leaders of the pro-Yushchenko party signed an agreement that gives Tymoshenko's party the right to name the prime minister -- virtually assuring she would get the post -- and allows Yushchenko's party to name the parliament speaker.

Bertrand Cantat was sentenced to eight years in prison.

The two parties also missed a chance to form the government together following the March 2006 parliamentary election, disappointing supporters.

The signing appeared to be a response to Yushchenko's tacit endorsement of the so-called Orange coalition. Yushchenko urged the two forces to quickly form a cabinet.

The document, however, had no official force, since a legally binding coalition agreement can only be signed by parliamentary factions after the legislature convenes. No date has been set.

Her divorce attorney, Laura Wasser, resigned last month as her legal representative after telling reporters the singer "just wants to be a mom."

The traffic charges are the latest in what has been a difficult year for the former teen sensation. Timeline: Britney Spears in the news »
