Carrie Underwood's Las Vegas Bachelorette Party

How did the country music superstar say goodbye to single life? Find out now.

The wedding bells are getting really loud for Carrie Underwood and hockey star Mike Fisher.

Just a week after Fisher had his bachelor party in Miami, the country music princess was in Las Vegas this weekend celebrating her last days of singlehood...

Joined by a dozen or so friends and family members, Underwood was spotted on Friday at Lavo nightclub. Wearing a costume tiara, the singer held court in a VIP booth. She and her pals, who were waving around blue feather boas, sipped on Hpnotiq cocktails and stood on the banquette for some dancing.

Underwood and Fisher will reportedly say their I do's on July 10.

Underwood wasn't the only celebrity bride-to-be whooping it up at her bachelorette party this weekend. Devil Wears Prada starlet Emily Blunt, who is engaged to The Office star John Krasinski, was toasted by friends (including Amy Adams) at L.A.'s Soho House on Saturday night followed by dancing into the wee hours at Trousdale.

In other celebrity sightings news, True Blood's Ryan Kwanten was spotted in Montauk, New York getting his rest and relaxation on. Not only did he do some surfing, but he took a class at Love Yoga and enjoyed some pampering at the Maybelline New York and Garnier Surf Salon at the Surf Lodge. At night, he hit the Like concert at the Lodge and also spent some time at the AXE Lounge in Southampton.

A few days earlier, Beyoncé and hubby Jay-Z helped her sister Solange Knowles celebrate her 24th birthday with a poolside party for about 20 people at The Empire Hotel in New York City.

Back in L.A., Tom Hanks did some nightclubbing, too. He was at Bardot sipping a Corona at the wrap party for Larry Crowne, a dramedy he not only stars in, but also directed and cowrote.
