Jamie-Lynn Sigler had the bachelorette weekend of a lifetime.

The Sopranos alum headed to Las Vegas over the weekend with pals including Lance Bass and Once Upon a Time‘s Joanna Garcia. On Friday, Sigler and her friends celebrated at Planet Hollywood, enjoyed dinner at Nobu and took in a performance of Absinthe at Caesars Palace. Sigler and her guests had double the fun, as it was a joint bachelorette weekend for her and one of their mutual friends.

“I had one of the most memorable weekends of my life with my closest friends,” Sigler tells PEOPLE.

Sigler, 34, has been engaged to baseball star Cutter Dykstra since 2013.

On Saturday night, they brought the party out to a Chippendales show, the High Roller and then to Omnia.

Despite all the fun, Sigler says she actually had to be convinced to have a bash.

“I was not into doing a bachelorette party, but when one of my best friends, Stephanie Herman, who is also getting married, pitched the idea of a joint one our friends ran with it,” says Sigler. “Our dinner at Nobu was amazing. The performance at Absinthe Vegas and the Chippendales show allowed to really cover it all in one weekend.”
