EXCLUSIVE: The monkey of Malibu! Leonardo DiCaprio wears chimpanzee mask as he helps scantily clad women into car after dinner

On Saturday night he was spotted enjoying a dinner date with on-off girlfriend Toni Garrn.

But the day before, Leonardo DiCaprio was seen entertaining a group of scantily clad women – while wearing a chimpanzee mask.

The actor is believed to have gone undercover in the disguise before making his way out of Nobu in Malibu, where he dined at a Halloween dinner with Australian businessman James Packer.

He was then seen holding a car door open while ushering Brody Jenner's ex-girlfriend Bryana Holly and two mystery women – each sporting a very revealing costume – inside.

Along with his ape mask, Leonardo was clad in a blue plaid shirt, dark jeans, black slip-on shoes, and a shell necklace.

Oddly, it was only the women who were really dressed up, with Leo and another party-goer armed with masks, and Packer dressed casually in regular clothing.

Although it seems the 39-year-old and his pals were off to an after-party, by the following evening he only had eyes for Toni, 22.

The pair were seen heading into Spago in Beverly Hills for a romantic meal, and were both dressed down for the occasion.

Leonardo and Victoria’s Secret star Toni were rumoured to have called time on their relationship in September, but they were then spotted playing tennis together last week.

The Wolf Of Wall Street star certainly seems to have a type in the form of stunning models, and has also dated Gisele Bundchen, Bar Refaeli and Erin Heatherton in recent years.

Leonardo is currently filming period drama The Revenant, based on the true story of fur trapper Hugh Glass and adapted from the book of the same name.

The star will play the protagonist – who sought revenge against the companions who robbed him and left him to die after he was mauled by a bear.
