Singer Nick Carter has invited fans to attend his birthday celebrations as part of a charity fundraiser.

The Backstreet Boys star turns 33 on 28 January (12), and to mark the occasion he is staging a fan event in Las Vegas to raise money for good causes.

Carter will auction off 10 guest spots and the winners will share dinner with the singer on 26 January (12). They will also be treated to a special acoustic show and the top bidder will be allowed to ride in a limousine with Carter on the way to the venue.

In a post on his page, Carter writes, "Hope your (sic) coming to my birthday in Vegas January 26th. Lets do a limo and dinner... No seriously it's happening."

A portion of the proceeds from the auction will be given to charity.
