Taking to Instagram on Friday, the Uncommon James founder — who split from husband Jay Cutler earlier this year — posted a bikini-clad photo of herself with hairstylist pal Justin Anderson, offering a cheeky comment about the longevity of their friendship.

“Longest relationship of my life,” Cavallari, 33, captioned the post.

Anderson, who is engaged to boyfriend Austin “Scoot” Rhodes, also shared a snap of the twosome.

“She tried to say she wasn’t in the mood for a picture… cavallari, calm down. ♥️ @kristincavallari #bff,” Anderson posted to his page.

Cavallari’s post was shared the same day Cutler addressed dating rumors after he was linked to Fox Nation’s Tomi Lahren.

“Only lady in my life,” Cutler captioned an Instagram video Friday of his beloved mini-cow. “Be better internet.”

Cavallari and Cutler announced their divorce in April. They share three children together: sons Camden, 8, Jaxon, 6, and 4-year-old daughter Saylor.

Last month, Cavallari gave Instagram a dreamy throwback when she reunited with her former “Laguna Beach” love interest, Stephen Colletti. The two are just friends, according to reports.
