Kristin Cavallari celebrated her birthday in style!
The reality star, who turned 29 on Tuesday, took to Instagram on her big day to show off her stylish look and post-baby bod during a birthday outing with her mom.
"Birthday lunch attire with my momma," she captioned the photo.
In the pic, the mom-of-three rocked a gray jacket with leather sleeves and a fur collar, which she paired with a basic sweater and some dark jeans. She finished the look with a black purse, pointed toe booties and a chic felt hat.
Kristin welcomed her third child, daughter Saylor, with hubby Jay Cutler in November -- and she looks absolutely amazing!
She also took to her app on Wednesday to share the first full photo of her new addition.
"Here is my little angel, Saylor," Cavallari wrote. "I couldn't have asked for a better baby. We're very lucky to have such a sweet, easy girl, especially since she's the third one! I guess there was no other option! Happy new year, everyone."
While "The Hills" alum is celebrating her new addition, the past few weeks haven't been easy for the star. Last month, news broke that Kristin's brother, Michael Cavallari, had been found dead three days after he was reported missing.
The blonde beauty, who is also mom to sons Camden 3, and Jaxon, 1, reflected on her year of highs and lows in a post after the new year.
"Last night was the second time I've put makeup on in over 5 weeks and left the house (besides the grocery store and taking Cam to school)," she wrote. "Even though I shed a few tears, it was a really nice night and felt good to be out. 2015 brought my sweet, baby girl but it also took my brother's life. Hoping for no extreme highs and lows this year. Happy new year, everyone."
