Britney Spears checked in and out of a hotel for the third time this week.  Her stay was quick before leaving with a guy in a white Lamborghini.

TMZ cameras caught the Britster at a gas station on Pacific Coast Highway last night, proudly showing off her terrier while someone pumped gas for her. From there, Spears hightailed it to the Viceroy hotel in Santa Monica, bringing her brand of crazazy for yet another panicked hospitality staff to enjoy.

Sources tell TMZ that Brit left the hotel with an unknown man in a white Lamborghini just before 2:00 AM, though it’s not clear if she returned. We hear she pulled the same express check-in-check-out at the Four Seasons in Beverly Hills the other night.

She needs help!  Either she doesn’t want her kids or she thinks that she can continue to do whatever the heck she wants and that she will eventually get them back.  Most mothers, who lost their kids to their ex-husband, would be no their best behavior for the judge to witness.  Maybe she thinks the custody judge doesn’t read TMZ or Bumpshack.
