And they're off!

Scott Disick is taking to the skies. The reality star, who shares kids Mason, 6, Penelope, 4, and Reign, almost 2, with Kourtney Kardashian, jetted off with his two oldest children on a trip to Chicago.

"The troops," he wrote next to a photo of himself with the youngsters as they boarded their private flight.

Later, he shared a photo of Penelope lounging in her seat with the caption, "The sunlight in my life."

Mason, who's looking all grown up, also posed for a sweet pic. "And the boss in my life," Scott, 33, cheekily wrote.

Though Scott originally split from Kourtney last year, it's looking like the couple may have reunited in recent weeks. We're so happy to see this family together again!
