A new Irish-American coupling could be on the cards – well, at least if a certain Oscar-less actor gets his way.

Leonardo DiCaprio was celebrating into the wee hours of Monday morning after scooping the Best Actor nod at the BAFTAs on Sunday, and he invited one very familiar Irish face to party alongside him.

According to sources in The Sun, Irish MTV presenter Laura Whitmore caught Leo's eye early on in the night, and was invited back to his penthouse suite at London's Rosewood Hotel for an all-nighter.

"Leonardo was completely taken by Laura," an insider claimed. 

"She was playing it cool but he made a beeline for her and they instantly started flirting.

"She loved the attention and they were all over each other, getting on like a house on fire."

Ms. Whitmore wasn't the only beauty present for Leo's celebratory party – supermodel Lily Donaldson is also said to have showed up – but Laura was certainly getting most of his attention, according to the source.

"He [Leo] was all over Laura until well after 5am," they said. "At one point he held her face in his hand."

Of course, while Leo might have fallen for the Bray native, we can't forget that she is still presumably in a relationship with rocker Rory Williams, who she has been seeing since last autumn.

However given how determined she is to keep her private life out of the media, there's no knowing if the pair are indeed still an item.

"I don't like talking about things, as you know, with personal stuff, because it is no one else's business," Laura said in a recent interview. 

"That's what my friends are for."

Laura has yet to address the Leo story on social media, but her rep did weigh in, telling the Irish Mirror that the claims of her "spending the night" with him were false.

"She was with a group of people who were all part of the BAFTA celebrations at no point did she spend the night with him."

Looks like we'll need to watch this space…
