Justin Timberlake "happy with his pop tag"

Justin Timberlake has revealed that he's happy with his pop tag on US TV.

The former N'Sync star told Barbara Walters on '10 Most Fascinating People of 2007,' "pop is short for popular, so I don't think you can be too sad abut being in that category."

Timberlake, who has had a string of high-profile relationships, first with Britney Spears, then with Cameron Diaz, revealed he's enjoying his relationship with actress Jessica Biel.

Timberlake, 26, said: "She's a wonderful, wonderful person."

Host Walter then probed further, asking if I thought it will last. Timberlake replied: "Well, I'll work on that. So far, so great."

The singer also spoke of winning an Emmy Award for sketch, 'Dick in a Box' on Saturday Night Live with comedian Andy Samberg.

He joked: "Well you know, it's a thoughtful Christmas gift for somebody."

Timberlake was recently named by US music magazine Rolling Stone as the 'New King of Sex.'

Timberlake told Walters: "I'll hold onto that title for as long as I can."
