JT hates casual sex

Justin Timberlake thinks that casual sex is a "bad idea". The 'Sexyback' singer, who recently split from actress Jessica Biel, says that getting "intimate" with someone without being in a relationship with them only leads to emotional heartbreak.

"It's a really good idea until it becomes a bad idea," he reveals. "It probably becomes a bad idea really fast. If you're going to be intimate with someone at some point somebody's going to feel something."

JT was recently linked to Tron actress Olivia Wilde.
