But Oprah Winfrey can get even a closemouthed star to come out of his shell. When Timberlake came on her show on Wednesday, he spoke about his ex-girlfriend Britney Spears and his current gal Jessica Biel - even though he didn't mention her by name.

Oprah asked Justin, "What do you think is going on with Britney?" He replied, "I don't know, to be honest with you. I haven't spoken to her in years. I mean, there's no ill will – I have nothing but love for her. It's funny because we dated each other at a time ... wow, I haven't talked about this in a long time. It's interesting."

When Oprah pressed for more details, Justin said, "We were teenagers, you know?" Oprah chimed in,

"Yes, famous teenagers." To which, Justin responded, "I think that's basically the best way to describe what happened to us. I think she's a great person, and I don't know her as well as I did. What I do know about her is she has a huge heart, and she is a great person."

Timberlake did reveal, "I'm dating someone, but all I can tell you is she smells lovely." Though Biel's name did not come up, Timberlake said, "I get pretty romantic around her." He claims that he sings to her sometimes.

Justin also admitted that he and his girlfriend use webcams to chat. Of the experience, he says, "Technology is a wonderful thing sometimes. I find that to be really cool, when you can actually see someone's face. I do it with my friends, as well, just to have a conversation back and forth. It just makes you feel closer, that's all."
