The Cartier International Polo day is a gala event in which most of the attention is supposed to be on the horses.

Sneaking a peek: Leonardo DiCaprio attracted attention at the Chinawhite party, but he only had eyes for Ashley

But no-one seemed to have told Leonardo DiCaprio, who only had eyes for a Pussycat yesterday. The 34-year-old actor, who flew to the UK from Madrid after dining there with his mother Irmelin on Saturday night, spent the afternoon at the Windsor bash wooing Pussycat Doll Ashley Roberts, 27. The pair ended up partying into the early hours today at Mayfair bar Whisky Mist.

What's new Pussycat? Ashley yesterday

Chinawhite nightclub laid on the post-match hospitality immediately after the polo, where the actor found himself in the familiar position of being smothered by female attention. Perhaps the girls read in the London Eye last week that Leo is looking out for an English Rose type.

But his entourage was quick to snuff out any unsolicited conversations with guests who weren't up to scratch. Our spy said: “Leo came in through the back and was immediately directed towards his private table. He was swarmed by beautiful ladies, including Ashley. He spent about two hours getting to know his new friends, eventually asking them if they'd join him at Whisky Mist.”

Once back in the West End, where Leo has been based while filming new movie Inception, he proceeded to splash out £6,000 on Dom Perignon champers for the ladies. We're told: “Leo's table was surrounded by some of the girls he had met at the polo. But he seemed more interested in talking to Ashley than anyone else and the pair were getting on really well.”

Leo wore a baseball cap to hide his face — despite the polo officials' “smart casual” dress code — and sneaked out through the bar's back entrance at 2am today.
