The Hollywood actor's security was reportedly spotted escorting Roxy Horner - who also used to date British reality TV star Joey Essex - back to his London hotel after enjoying an evening out at nightspot Chiltern Firehouse, and the pair are said to have "hooked up".

A source told The Sun newspaper: "Leo and Roxy met a while ago in LA and he was taken with her.

"When he got to London for the BAFTAs he immediately said they should hang out. When they finally met last night the sparks were flying. They were hooking up throughout the night."

Roxy's pals, including Geo Rushby, were also said to have been escorted back to the Rosewood Hotel, but the movie star - who won the Leading Actor prize for his movie 'The Revenant' at the Sunday night's (14.02.16) ceremony - travelled in a different car.

The 24-year-old model - who previously described Leonardo as "the definition of sexy" in a tweet - posted a Snapchat video dancing to song 'Work', which is by Leonardo's rumoured girlfriend Rihanna, in the early hours.

This comes just days after British TV presenter Laura Whitmore was said to gone back to the 41-year-old star's hotel on Sunday night and partied until the early hours.

While Leonardo has recently been linked to Rihanna, the Bajan beauty confirmed earlier this month that she is "single" and has no time for a "steady relationship".
