What do Sheryl Crow, Lance Armstrong and Las Vegas have in common? Apparently Vegas became the stage for Armstrong to act out and the reason for Crow to walk out.

According to publicists, Sheryl Crow and Lance Armstrong have called off their wedding.

According to In Touch Weekly — yes, one of those lovely tabloids —Lance and some friends kicked off a January 24 visit to Vegas with dinner and four bottles of wine at Spago in Caesars Palace. Then they hit the casino floor and enjoyed gambling and flirting.

According to the tabloid, "Lance was completely drunk and flirtatious," and onlookers were shocked when he stumbled out of the club at 2 a.m. with a woman.

Apparently Lance was seen later that week in Beverly Hills at Mastro's Steakhouse where he was on the prowl and flirting with every girl in site.

Keep in mind it’s rumored the couple split in mid-December so Lance and Sheryl, in the words of Friends’ Ross, could have been on a break at the time.

The seven-time Tour de France winner and the Grammy-winning pop star Sheryl Crow officially announced their split on February 3. Guess there’s no Vegas wedding in sight for the celebrity couple.
