Kristin Cavallari, known for her time on *The Hills*, is once again single after her recent breakup with Mark Estes. The couple, who began dating in February 2024, called it quits, a fact Cavallari confirmed during Alex Cooper’s *Unwell* tour. According to *PEOPLE*, the 37-year-old Cavallari and 24-year-old Estes had initially gone public with their relationship on Instagram, where Cavallari posted a sweet selfie captioned, “He makes me happy.”
Their relationship seemed to be flourishing, with Cavallari posting photos from their romantic getaway to Greece, where they were seen enjoying intimate moments together. Despite this, the relationship ended not long after the trip.
Cavallari had expressed happiness during her time with Estes, with sources noting that her friends hadn’t seen her this happy in a decade. Estes had reportedly been great with her three children, Camden (12), Jaxon (10), and Saylor (8), whom she shares with ex-husband Jay Cutler.
While the breakup may have come as a surprise, sources say that Cavallari is focusing on enjoying life and embracing the moment, without putting too much pressure on her relationships moving forward.
