With her single days dwindling, Carrie Underwood had one last hurrah with her girlfriends in Las Vegas this weekend.

"Around midnight on June 25, Carrie landed at Las Vegas' Lavo nightclub with about eight girlfriends," a club insider tells Life & Style. "She was wearing a minidress and a sash that said 'bachelorette.'"

Surprisingly, Carrie's party wasn't out of control. "It wasn't a rowdy bachelorette party," the insider says. "No shots or singing or anything like that. It was just a group of girls dancing and having fun!"

However, Carrie's fiancé Mike Fisher went a little more wild with his bachelor's party last weekend. He and his friends partied the night away while at Mansion in Miami.

Carrie and Mike will tie the knot on July 10 outside of Atlanta.
