With under two months to go until her new series debuts, Private Practice star Kate Walsh has plenty to celebrate. But last weekend was cause for something celebratory and altogether different - a bachelorette party in her honor!

Among the friends on hand to help Kate Walsh celebrate at Tao nightclub in Las Vegas' Venetian hotel were former co-star Sara Ramirez and Keisha Chambers, the wife of another Greys Anatomy mainstay, Justin Chambers.

While no date has been announced that we're aware of, it looks like Kate's wedding could be in the works for the near future! Kate Walsh, 39, got engaged to Fox studio executive Alex Young earlier this year.

Kate Walsh and friends clearly had a blast in Sin City.

The premiere of Private Practice is set for Wednesday, September 26, at 9 p.m. We're looking forward to seeing Kate, Taye Diggs and the rest of the cast of this promising series make their debut!
