Pamela Anderson received a $195,500 bottle of champagne for her 44th birthday.

The former 'Baywatch' star - who turned 44 on July 1 - was sent over the expensive 30-litre of Armand de Brignac Ace of Spades by a mystery man as she celebrated in the Chateau nightclub in the Paris Hotel, Las Vegas, on Sunday (31.07.11).

An onlooker told the Daily Mirror newspaper: "Pammy was gobsmacked. It was the equivalent of 40 regular-sized bottles. It was bigger than her..."

The blonde sex symbol - who was previously married to music stars Tommy Lee and Kid Rock - donned a white mini dress as she partied, surrounded by men and sipping champagne.

Pamela - who has two kids, Brandon, 15, and Dylan, 13, from her previous relationship with Tommy - was also presented with a three-tiered birthday cake, which was decorated in a Pink, black and white design with a bow on top.

The 44-year-old actress may be opening more champagne soon after recent reports suggested she is set to appear on British TV reality show 'Celebrity Big Brother', which she came close to signing up for last year before pulling out when ex-husband Tommy refused to participate alongside her.

She said: "I am very excited about the show. I will just be myself and have fun with the contestants in the house."
