Britney does the bare act again!

Britney Spear's bikini pics taken just five days before her head-shaving incident highlight another example of her erratic behaviour.

The singer’s pics that have recently come to light show her posing in a teeny thong with two night spot resident dancers at the Club One nightclub in New York.

The 25-year-old was partying with pals at the nightclub and went backstage to chat with dancers. Once there, she ended up stripping down to her essentials, the Sun reports.

The Toxic singer, who has been in the news for her disastrous interview to OK! magazine looks quite happy and relaxed in these playful snaps.

The pictures also show the two dancers in their bare minimums with one dancer sporting a thong even tinier than Britney’s.

Less than a week after posing for the pics, on February 16 Spears entered an off-shore drug rehabilitation facility in Antigua where she stayed for less than twenty-four hours.

The following night, she went to a haircutting studio in Tarzana, California and subsequently shaved her own hair off with clippers.

Victoria warns Paris Hilton

Victoria Beckham has reportedly warned Paris Hilton to stay away from her soccer star husband David. The Spice Girl, who moved to Los Angeles with David and their three sons earlier this month, was said to be furious when she heard the hotel heiress had described the Los Angeles Galaxy player as "hot".

Now she has allegedly told friends that Paris and other young Hollywood stars - including Lindsay Lohan and Britney Spears - better keep their hands off David.

A source told a British magazine, "This move to Los Angeles means everything to her. She is happier with David than ever and sees this as an exciting chapter for her and their boys. Although she trusts David 100 per cent, she will not tolerate any of the Los Angeles party girls making a move on him, or seeing him as fair game.”

"She wants this to be very clear from the start - David is a devoted family man and these women should forget about trying it on with him. "The young Hollywood club crowd, such as Lindsay, Paris and Britney, are positively salivating over David," the source added.

Last week, it was claimed Victoria had turned down Paris' offer of friendship. Paris is reported to have said about Victoria: "We could be soul mates." However, the ‘Wannab' singer apparently told a pal: "Over my dead body!"
