Now that's how you celebrate your 30th birthday.

Kristin Cavallari, who rang in her next decade of life on January 5, was treated to a very festive surprise party all put together by her NFL quarterback husband Jay Cutler. The Laguna Beach and The Hills alum took to Instagram today to proclaim her gratitude, and posted an adorable snap of them sharing a kiss at the event.

"This is the only somewhat decent picture I have from last night (and we're both clearly sober) but Jay really went all out for my 30th birthday," she wrote alongside the cute image. "He threw the most amazing surprise party and made me feel so special and loved and I will forever be grateful for this man, my family, and all my amazing friends. I am the luckiest girl in the world to have such incredible people in my life."

Cavallari and the football player have three children together—sons Camden Jack, 4, and Jaxon Wyatt, 2, and daughter Saylor James, 1—and will celebrate their fourth wedding anniversary later this year.

Sounds like a keeper to us.
