Kristin Cavallari, Jay Cutler Baby: Reality Star Celebrates Her Birthday With Husband, Kids & Close Friends [PHOTOS, VIDEO]

Happy Birthday, Kristin Cavallari!

Kristin Cavallari Opens Up On Getting Little Sleep

The reality star is celebrating her 29^th birthday on Tuesday where it appears that she's keeping it fairly low-key. According to E! News, she and her husband are having an intimate dinner with a few close friends after she has lunch with her mother.

A source told the site that Cavallari is in "good spirits" for her birthday, which is positive news for her. Unfortunately, her brother died last December after being reported missing. It also happened to be near the same time she gave birth to her first daughter, Saylor.

Chatter On Kristin Cavallari's Gig From Last Year

Over New Year's, the former star from The Hills posted a photo of herself on Instagram with her spouse, Jay Cutler, as they have a romantic dinner together. In the caption, Cavallari wrote how 2015 was a time of something great as well as something tragic since she had her daughter and lost her brother. So for 2016, she's hoping it won't be an extreme roller coaster.

 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). 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.

Cavallari managed to keep it together for Christmas since she added a picture of herself holding onto her little girl. For the baby's first holiday season, the two seem thrilled to celebrate with each other along with Cutler and the couple's two sons, Camden, 3, and Jaxon, 1.
