Taylor Lautner has been spotted smooching his co-star

An eyewitness said: "He was sitting really close to Billie, whispering in each other's ears twice and kiss. (sic)"

The pair were also said to be close during the evening in other ways with the 24-year-old beauty spotted stroking the 'Twilight' star's chest.

The witness added to E!: "They've been staring in each other's eyes and she's been stroking his chest because his shirt is unbuttoned."

Last year, Taylor was romantically linked to Raina Lawson after splitting from Marie Avgeropoulos, who he met on the set of action movie 'Tracers'.

He has also been previously linked to his 'Abduction' co-star Lily Collins and singing sensation Taylor Swift, who he recently admitted he had a "fun few months" with.

The actor said: "It was a good time. It was a fun few months there."

Taylor was mocked about his relationship with Swift by his 'Scream Queens' co-stars Lea Michele and John Stamos during a recent Facebook Live chat.

The former 'Glee' star said: "You dated Taylor Swift. I remember that. Should we talk about it?

"Didn't she write a song about you?"

Taylor replied: "That's what she does. She writes songs."

John then asked which song his pal had inspired, and Lea replied: "I think it was on the one about a sweater and a hat."

The 'Cuckoo' actor appeared visibly uncomfortable and tried to change the subject, simply saying: "That's hilarious."

But he confirmed he listens to her music.
