Socialite PARIS HILTON has cemented her party girl persona with a 50 per cent stake in one of London’s hottest bars.

The 24-year-old hotel heiress was given a share in swanky Kensington club The Collection - a favourite haunt of British royal PRINCE WILLIAM - as a gift from her parents who hope the venture will develop the blonde beauty’s business skills.

A source tells British newspaper the Daily Mirror, “This is just the start for Paris, and her family would like her to make more investments in London bars.

“She has the looks and personality to move their success into another arena as the bar industry is huge.”

An employee at the plush nightspot confirms: “It’s true - Paris is a shareholder but so far she likes to take a back seat and sit back and enjoy it.”
