I joined the Scottish heartthrob on a wild night out in Tinseltown where he showed me he will not be tamed by any lady.

The 300 star has been unlucky in love with JENNIFER ANISTON. And this week he sent her a clear message about their relationship.

I saw Gerard get up close and personal with THREE beauties at plush hangout Chateau Marmont. One of the ladies left hot and bothered was Sheila Shas, who got his number AND a promise of a date.

"I can't believe Gerard Butler just came onto me," she squealed in my ear. Gerard arrived at the party - featuring DJ SAMANTHA RONSON - in the early hours of Thursday morning with a group of friends. But my bombshell observations will devastate Jen, who was sure she could tame the notorious ladies man.

My LA source told me: "Jennifer thought they could be the real deal. The fact he's going around flirting with other girls and swapping numbers proves that's not the case."

Jen won't be the only Hollywood WAG to be unhappy about my night out. LEO DiCAPRIO's girlfriend BAR REFAELI needs to give her man a talking to as well.

The Shutter Island star showed up, also looking for some attention of the female variety.

Needless to say it wasn't long before he got some - I watched as FIVE Beverly Hills babes draped themselves over Leo.

He was particularly taken by one tall leggy blonde and after some serious flirtation, left the party with her through a side exit.
