Is Britney Spears Ready For Husband #3?

They've only been dating a few months, but it's safe to say that Britney Spears and new boyfriend Charlie Ebersol are head over heels. But, are they headed to the wedding chapel? "You never know," the pop star told Extra in a new interview. "Who knows?"   Hmm. Not yet a no, not yet a yes.  "I'm very blessed to have him a part of my life," Spears added of her beau, whom she started dating last fall. Indeed, the TV writer and producer has been featured prominently on her Instagram account, most recently seen enjoying a "family lunch" with Spears and her two young sons.  He's also inspired a wardrobe change. Spears told Extra that she wears an "I Love Charlie" vest during her Vegas show. K-Fed never got that kind of TLC. "He's like, ‘You're the sweetest girlfriend in the whole world,'" the 33-year-old said of Ebersol's reaction. "He was really happy that I did that. It's kinda cool." Aww. If these two are wedding bound, it would mark Spears' third down the aisle. We know she's living in Vegas right now, but maybe this time she can shell out for something a bit more special than wedding numero uno with Jason Alexander?
