0217-leonardo-laura-the-sun-01Leonardo DiCaprio keeps winning -- both for his role in "The Revenant" and with the leggy blonde contingent, because he had another one in his ear at a BAFTA after-party.

The latest Leo conquest -- Irish TV personality Laura Whitmore. They looked very cozy Sunday night in London, and while she is a hot chick and he is Leo ... sources close to Laura say it's not what people think.

We're told Laura was working, interviewing celebs at the award show -- and their convo was nothing more than casual, friendly cocktail party chatter. Leo would call that foreplay, but the source insists it was all "innocent."

Still ... Laura would fit right in with the rest of them.
