Kristin Cavallari is ringing in the next decade with all her loves.

The reality star, designer, and home chef took to Instagram to show off her 30th birthday celebration alongside husband Jay Cutler. The mom-of-three shared a sweet snapshot of the pair kissing at the star's birthday party.

"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. "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."

The couple — who are parents to Camden, 4, Jaxon, 2, and Saylor, 13 months — looked positively in love as they rung in Kristin's big 3-0.

While the evening capped off with a surprise party, it looks like the occasion was an all-day celebration that even included some well-deserved treats.

"Birthday breakfast cupcakes… why not!" Kristin wrote earlier in the day. "#ByeBye20s #Hello30s."

Looks like one serious celebration. Happy birthday to the star!
