Britney Spears and Paris Hilton appeared to have put their differences behind them when the former party-pals were pictured together at a Beverly Hills bash on Friday.
However, onlookers at the Scandinavian Style Mansion event, hosted by Sharon Stone, claim that the meeting was anything but friendly – and nearly ended up in a cat-fight.
A trash-tastic Britney – who sported a new blonde hair weave and looked to have fallen asleep on the tanning bed – was celebrating her 26th birthday with cousin and former assistant Allie Sims when the alleged clash happened.
According to the Daily Mirror, bodyguards had to be called in when the couple squared up for a fight.
Their insider said: "They were shouting at each other - it nearly ended in a punch-up!"
A fight could have been disastrous for Brit – one tug and those ropey hair extensions would have been history.
