The mother of three has returned to California and reunited with a few of her MTV co-stars. On Tuesday, Cavallari, who announced her split from husband Jay Cutler earlier this year, posted a photo with Stephen Colletti, her former fling on Laguna Beach, along with the caption, "2004 or 2020?!"
In the dimly lit pic, the 33-year-old reality star is sitting on Colletti's lap with her arms around him.
Now that she's back on the West Coast, Cavallari is spending time with a lot of old friends, a source tells ET. In addition to her selfie with Colletti, she also shared a pic of her kids hanging out with her other Laguna Beach co-star, Alex Murrel's, children.
"Kids crew," she captioned the summer photo.
And while Cavallari and Colletti's cozy pic together is sure to spark romance rumors, a source close to the newly single celebrity tells ET that the exes are just friends.
Though there has been no rumblings of a Laguna Beach reboot, Cavallari was to make a cameo on the upcoming season of The Hills: New Beginnings before quarantines were put in place amid the coronavirus pandemic.
