Scott Disick and Kourtney Kardashian are the epitome of friendly exes.

Kardashian, 41, posted a sexy photo of herself wearing a silver one-piece bathing suit on a boat, captioning it, “lake ya.” The photo obviously caught 37-year-old Disick’s eye, as he cheekily responded in the comments, “What a lake er.”

It’s the latest in a series of comments that have fans feeling encouraged that the former couple, who share three kids together, could one day reunite as they’re both single.

Kardashian teased fans when she posted a picture wearing Disick’s flannel after he and Sofia Richie broke up.

In return, Disick complimented her look, writing, “cute shirt.”
