Kaley Cuoco Tied the Knot!

Kaley Cuoco rang in 2014 as a Mrs. — bazinga!

The Big Bang Theory star, 28, married 26-year-old tennis player Ryan Sweeting at Hummingbird Nest Ranch in Santa Susana, Calif. last night. They had around 150 guests in attendance, including Cuoco's Big Bang co-star Johnny Galecki and Bachelorette alum Ali Fedotowsky. The blushing bride shared a sweet "just married" snapshot with her fans on Instagram confirming the news. The caption read: "Yep :) #thesweetings"

Cuoco wore a custom-designed petal pink strapless tulle ball gown by Vera Wang. With its sweetheart neckline, detailed bodice, and hand appliquéd Chantilly lace accents, it's a romantic yet fashion-forward choice for the starlet, in contrast with her television persona, Penny. She accessorized it with a nude tulle veil with pink floating appliqués. People and Us Weekly report that she also wore a short red dress - we can't wait to see more photos!

The couple made headlines when they got engaged after just three months of dating. "You know by day two I was like, 'Oh, my god.' It was so unbelievable," she revealed during an appearance on Ellen. "I said, 'This is it, this is it.'"

Cuoco told Craig Ferguson that her dreams for the big day included having a cake in the shape of her dogs' heads ("I'm obsessed with my dogs") and riding in on one of her horses ("I secretly kinda want to do that").

Stay tuned for more details on her fire-and-ice-themed bash! Congratulations to the happy couple.
