Pamela Anderson the party animal dances on top of a car roof with red white and blue American flags pinned on her chest

At 45-year-old, Pamela Anderson is showing no signs of slowing down.

The party-loving actress was seen dancing on top of a car in a carpark in Malibu during Fourth Of July celebrations yesterday.

The Baywatch star caused a frenzy as she climbed onto the vehicle in a tight white dress with red white and blue American flag adorning her famous chest.

The former showgirl amazingly kept her balance in a pair of towering heels as she showed off her moves.

But it wasn't before too long that she removed them to hitch up her dress.

Below a bevvy of male fans snapped away with their iPhones with Pammie lapping up the attention.

Pamela is known for her hard-partying ways.

The 45-year-old wore a tight white dress with red white and blue American flag adorning her famous chest 

This despite having issues with her health - the actress revealed in 2002 that she had hepatitis C.

Anderson caught the liver disease by sharing a tattooist's needle with ex-husband Tommy Lee, the Motley Crew drummer.

The star has previously told People magazine that she controls the infection with medical help.

'I’ve had liver biopsies. I get checked every single year, my doctor told me just keep doing what you are doing.

 'I also have the kind that’s easiest to control. There is no cure for it, so the important thing is to encourage people to get tested and not be ashamed.

'People get embarrassed as you get it from blood-to-blood contact, but it is not just junkies who have it,' she said.

Hepatitis C causes inflammation of the liver, which can lead to cirrhosis, liver cancer and liver failure.

Meanwhile, Pamela was recently in London to attend a party thrown by Prince Haji Abdul Azim of Brunei.

The blonde bombshell joined the likes of Mariah Carey and Raquel Welch to help Prince Azim mark his 30th with a lavish celebration at the world-famous Dorchester Hotel in the capital.

Prince Azim is famous for his legendary celebrations, with his birthday party in 2009 dubbed the 'Party of the Year' after he splashed out a reported £70,000 for flowers to deck out the event.

The prince is also known for his generosity, having previously presented Mariah with $6million of jewels.

 And it was Mariah and Pamela who seemed to hold the Prince's attention the most - Pam, handing the Brunei royal what appeared to be a birthday gift, and even standing up for what appeared to be a serenade during the celebration.

Huddled together in the centre of the room, the trio seemed to enjoy each other's company immensely, trading laughs and swapping stories during their glitzy evening out.

Pamela chose a figure-hugging halter dress for the occasion, showcasing her ample cleavage and toned legs.
