Kristin Cavallari and Jay Cutler have shared the first photo of their new baby girl.

The former "Laguna Beach" reality TV star posted a photo of her new daughter Saylor James Cutler and also apologized for missing her 10-year high school reunion on Sunday, according to The Huffington Post.

"Really sad about missing my 10 year high school reunion last night...so many people I wanted to see...but at least I have a good excuse," Cavallari posted on Instagram with the newborn's photo. Cavallari looks comfy in the photo, wearing a gray beanie and holding her little girl, who's wrapped in a pink blanket.

The 28-year-old gave birth to Saylor, her third child and first daughter with Cutler, last week. They are also parents to Camden Jack, 3, and Jaxon Wyatt, 18 months.

Cavallari and Cutler, 32, quarterback for the Chicago Bears, tied the knot back in 2013. They began dating in late 2010 and were engaged in April 2011. At first, the couple had called off the engagement in July 2011, but then reconciled in November 2011.

After growing up in Barrington, Illinois, Cavallari attended Laguna Beach high school in California, which is where her high school experience was filmed for the MTV show "Laguna Beach: The Real Orange County." Other people who starred on the reality show included Lauren Conrad, Stephen Colletti, Talan Torriero, Morgan Olsen, Trey Phillips, Christina Schuller and Lo Bosworth. The show aired from 2004 to 2006. It generated several spin-off shows, including "The Hills" and "Newport Harbor: The Real Orange County."

Cavallari has also appeared as an actress in "Veronica Mars," "Fingerprints," "CSI: NY," "Cheerleader Camp," "Spring Breakdown," "Green Flash," "Cane," "Wild Cherry," "National Lampoon's Van Wilder: Freshman Year" and "The Middle."
