Kristin Cavallari shares a throwback photo

“Flipping through #BalancingInHeels is a little trip down memory lane,” Cavallari, 29, captioned the sweet pic. “We were babies! Link in bio #LagunaBeach #HighSchool #TBT.” Cavallari and Colletti, 30, brought the drama when they starred in the MTV series Laguna Beach . 

The reality show — a prequel of sorts to The Hills — ran for three seasons, from 2004 to 2006, and helped kick off their entertainment careers. Cavallari now spends most of her time in the Windy City with her husband, Chicago Bears quarterback Jay Cutler, and their three children — sons Camden, Jaxon and daughter Saylor.
