Britney Spears was all smiles when X17 photographers snapped her photo on Tuesday in Los Angeles, but last week it was a completely different story!

Britney was onstage in Las Vegas performing at her residency gig, and she pranced around onstage and said, "Look how beautiful the girls are! Men, frankly, can suck my f*cking toe." Wait, what?!!

In June Brit Brit broke up with somewhat steady boyfriend Charlie Ebersol, but we also have to wonder if this might have something to do with the pop star being unhappy about performing in Sin City. Her contract expires on December 31, and she recently told E! News that's she's not sure if she'll renew it. "I haven't made up my mind," she said. "I really love doing the show. It's a lot, a lot of fun but I'm kind of torn right now. I don't really know what I want to do."

Hmm, what's this really about?! Watch the video below and tell us what you think!
