Jennifer Aniston's co-star says kissing her in 'We're the Millers' was "awkward".

British actor Will Poulter, 20, thinks it was "probably horrible" for the beautiful 44-year-old actress, who plays his mother in the new film, and his other co-star Emma Roberts, who plays his sister, to lock lips with him during a three-way kissing scene.

Speaking exclusively to BANG Showbiz at the UK premiere of the comedy at London's Odeon Leicester Square on Wednesday night (14.08.13), he said: "That was awkward. That was probably horrible for Jen and Emma, but [my character] loved it. That was my first three-way kiss ... it was fantastic!"

He added: "It was pretty surreal to have Jennifer as my mum. I love my mum, but we have a slightly different relationship in this film ... this film's a slightly dysfunctional family relationship."

Jennifer plays struggling stripper Rose Miller in the new movie, who creates a fake family with Jason Sudeikis' character David, in order to smuggle drugs across the U.S. border in an RV from Mexico and she really enjoyed working on the film.

Asked about her favourite memory from her time on the set, she said: "I would say working with the cast and the amazing luck we had with the improv we got to do, and being able to re-team up with people you respect and love. Plus, it's a really funny movie!"

Jason Sudeikis, director Rawson Marshall Thurber, The Saturdays, Joey Essex and Lucy Watson also attended the special screening.
