Kaley Cuoco is saying goodbye to single life with a big bang bash!

Kaley  who got engaged to Ryan Sweeting in September 2013 — celebrated her impending nuptials over the weekend with a star-studded bridal shower, according to Us Weekly.

The Big Bang Theory star's shower took place on November 23, with such pals in attendance as The Bachelorette star Ali Fedotowsky, Mean Girls' Lacey Cabert, and Big Bang co-star Melissa Rauch. Kaley's younger sister, Briana Cuoco, who was seen this season competing on The Voice, was also there.

Kaley wore a lovely floral-print dress and blue heels for the big day, and she had her hair in an elegant up-do. 

"Pre-holiday party with this beauty," Ali captioned an Instagram photo of herself cozying up to Kaley at the party. "LOVE HER!" Too cute!

And speaking of love, we're loving Ali's dress with all the little hearts on it. Any chance we can borrow that, Ali? Thanks a bunch.

It's been a busy month of wedding prep for the 27-year-old Kaley. Last weekend, she celebrated her bachelorette party with pals in Palm Springs.

We had assumed that Kaley and tennis star Ryan wouldn't be getting married until well into the 2014 wedding season. But with all this recent fanfare, we're thinking the two might actually be heading to the altar any day now! Either way, Kaley is going to be a truly gorgeous bride.

Do you think Kaley and Ryan will be getting married in 2013?
