Hollywood star Leonardo DiCaprio is clearly enjoying his new-found singledom — and we can reveal he's keeping his amazingly high standards when it comes to female companions.

We spotted him out last night on an intimate date with the ex-girlfriend of Jesse Metcalfe.

The Blood Diamond star, who recently split from his long-term lover Bar Refaeli, took stunning model Emma Miller on a dinner date in South Kensington.

Ladies' man: Leo DiCaprio out last night

Desperate Housewives star Jesse is bound to be peeved that Leo, 34, was romancing his former squeeze (after all, Leo does have something of a Titantic reputation with the ladies).

The actor took Emma to Collection, where he did his best to stay incognito with his regular trick of pulling a cap over his face — hardly the best outfit for a hot date.

Our mole told us: “The pair arrived separately and Leonardo was very keen not to be photographed. They left 10 minutes apart, and Leo then made his way to Maddox nightclub in Mayfair.

“His car stopped, and just when it looked like he was going to get out, it sped off again. He must have had a last-minute change of heart.”

Reports that Leo had split from Israeli supermodel Bar emerged last month, with many sources citing his refusal to commit.

Emma and Jesse split after being pictured together several times in April and May.

Leo is currently in London filming sci-fi thriller Inception, also starring Michael Caine and Marion Cotillard, with Memento director Christopher Nolan at the helm.
