Britney’s Bikini Weekend Before Rehab    ·    February 28th, 2007

Before checking in to Promises rehab center in Malibu for the second time, Britney Spears enjoyed a strange, bewildered day with two new friends.

Bright and early on February 17, a newly bald Spears arrived at L.A.’s chic Mondrian hotel, ready to catch some rays. But the star was denied a room due to lack of credit cards or cash.

By 11 a.m., an undeterred Spears, 25, had stripped down to a bra and panties poolside, then shaved her legs in the pool bathroom.

“It was sad,” says a source. “It looked like she really needed a friend.”

She got two – at least for a few hours. Around noon, Spears (then in a blonde wig) began chatting up a woman in the bathroom, who offered to loan the pop star a bathing suit.

Spears followed her new friend to her hotel room where — after changing into a borrowed bikini — she raided the minibar.

“She grabbed four or five bottles and just started mixing everything and drinking them.”
