News of more bizarre behaviour surfaces from Britney Spears.

Before checking into rehab the latest time around, Brit shocked hotel guests and staff with her behaviour, Us Weekly magazine reports.

It all happened at the chic Mondrian hotel in LA on the 17th February...

A newly bald Brit arrived at the hotel early in the morning and tried to check in.

However, when the star was denied a room due to lack of credit cards or cash, the singer strolled to the hotel pool... then proceeded to strip down to her bra and panties.

"It was sad," a source told the magazine. "It looked like she really needed a friend."

Next stop for Brit was the pool bathroom, where she shaved her legs while chatting with a woman.

When the lady generously offered to loan the pop star a bathing suit, Brit accepted and followed her new friend up to her hotel room.

But the bathing suit wasn't the only thing Brit wanted... the singer then raided the minibar for alcohol, according to the magazine's source.

"She grabbed four or five bottles and just started mixing everything and drinking them," said the source.

We're glad Brit's now getting well in rehab...
