Disick, who shares three children with Khloé’s sister Kourtney, dropped the hint in the comment section of a sexy Instagram post from Khloé, who wore a tiny black bikini from her latest collection for swimwear brand, Good Swim.

“Good Swim back in stock NOW,” the 36-year-old reality star alerted fans, leading Disick to acknowledge Thompson, 29, in his reply.

“@realtristan13 is a lucky man!” Disick, 37, wrote, according to a screenshot captured by The Shade Room.

Khloé also recently suggested that she and her daughter’s father may have reunited with a cryptic message to fans reading, “Not a secret, just not your business.”

A source previously told People that the Good American founder and the NBA baller reconciled this summer, almost a year and a half after Thompson’s cheating scandal involving Kylie Jenner’s former BFF, Jordyn Woods.

“Tristan is working hard to prove himself and has been a great dad to [the couple’s 2-year-old daughter] True,” the source said.

The pair reportedly decided to work things out during Khloé’s 36th birthday party. They also spent July 4th together and Thompson most recently left a heartfelt message within the comments of a photo of Khloé and True.
