Justin Timberlake has revealed that his mum caught him having sex at a young age.
The singer and actor explained that his mum "wasn't cool" when she caught him in bed with a girl.
"I was caught [having sex] one time," he told Elle. "My mum wasn't cool about it. I was too young to be in bed with a girl, so she was upset."
Timberlake is starring in upcoming romantic comedy Friends With Benefits opposite Mila Kunis, where two friends decide to make a no-strings-attached sex pact.
Kunis also insisted that it's difficult to have meaningless sex. She commented: "It is such a good idea - until it's a bad idea.
"Ultimately, it ends when someone wants to go and get serious with somebody. More times than not, a person catches feelings and somebody gets hurt. When a female orgasms, a hormone gets released. I've never met a girl who can have sex without an ounce of feeling."
Timberlake and ex-girlfriend Jessica Biel have apparently reunited.
