(Cover) - EN Showbiz - Olivia Wilde was upset she didn't get to lock lips with Justin Timberlake in her new film because she plays his mother.

The American actress stars alongside the Hollywood hunk in an upcoming science fiction film tentatively titled In Time. The stunning star, who is famed for her roles in TV drama House and 2010 movie TRON: Legacy, plays Justin's mom in the upcoming picture.

Olivia was disappointed that her casting meant there was no hope of a steamy love scene between the pair.

"I play his mom," she is quoted as saying. "The one time I get near him and I'm his mom! There's no way of sneaking a kissing scene with that."

The film is set in the future where people stop aging at 25 and must work to buy themselves more time. Olivia, 27, says the futuristic elements of the movie made filming "weird".

"It's a cool kind of sci-fi film where ageing stops at 25. I had to play a 60-year-old woman but not change myself physically. You're trying to have a kind of familial intimacy but not let it get weird and romantic. So it was kind of funny," she revealed. (C) Cover Media
