Britney Spears was in Las Vegas over the weekend, where she hooked up with -- of all people -- Mario Lopez from Dancing with the Stars. No word on whether there was any hanky-panky, but they were introduced at The Mint and were seen talking. Shortly after the duo -- along with a small group of people -- hit the Moon Nightclub, where they partied the night away. Mario was recently rumored to be hooking up with Eva Longoria – though Eva denies it because she’s still with “Tony, Tony, Tony.” Mario was married to Ali Landry for about 2.5 seconds -- while they were on the honeymoon, she learned he cheated on her during his bachelor party. Whatta catch!
