LONDON (AP) — R&B star Usher says he still feels 21, despite just celebrating his 34th birthday.

The singer partied in London with a host of British singing talent Saturday night before his birthday Sunday, including Leona Lewis, Tinie Tempah, Dizzee Rascal and JLS star Ortise Williams. But Usher says that's not where the party is going to end.

He says "it's really going to be a party celebration week as opposed to weekend."

In London to promote the computer game "Dance Central 3" for Xbox, the star says he danced all night at the bash and has no worries about becoming a year older.

"In some respect, I never really get old ... you know those kids that make an entire month their birthday? That's me," he told The Associated Press.
