A REP for Carrie Underwood says she and Tony Romo are "definitely not boyfriend-girlfriend," but it would be easy to think so. The 2005 American Idol winner (below) was at the Cowboys QB's 27th birthday party at a Dallas club last week: She led a Happy Birthday serenade, then the pair led the crowd in a rendition of Twisted Sister's We're Not Gonna Take It. Oh, and they were seen holding hands. Says Underwood's rep, the relationship is in the "really early stages." ... Rapper Lil' Jon, supermodel Christie Brinkley and WWE wrestler Edge are among the celebs blogging about the playoffs at NHL.com. The posts are passionate (most bloggers are fans of a team in the postseason) and sometimes poetic. Brinkley, a Long Island native, gushed of her Islanders, "these giants that become so graceful on the ice, they're all pure macho grace." ... As the moviegoing public is about to find out, Nelly is an accomplished bowler. (Until recently the rapper held the house record of 257 at his favorite lanes in St. Louis, his hometown.) The rapper says he will star in Rolling Thunder, a kegling movie in the works. "I can't really talk about it," he told MTV, "but we're working on a project with one of my alltime favorite pastimes."
