Britney Spears has finally come clean about her relationship with *NSYNC hunk Justin Timberlake, admitting to Rolling Stone magazine that she does "occasionally" cuddle up with "the cutest thing in the world." But she goes on to say that it's not "serious" between the two former "Mickey Mouse Club" stars. In the same article, Britney, who is hard at work promoting her new CD, "Oops! . . . I Did it Again," also addresses the lip synching issue, claiming that it's a video delay with big screen monitors at her concerts that makes it look like she's mouthing the words.
