Singalong!

Kourtney Kardashian and Scott Disick recently returned from a family ski trip to Aspen, Colorado — and they kept the fun going all the way back home.

Disick, 33, took to Instagram on Thursday to share an adorable video of himself singing “Twinkle, Twinkle, Little Star” with Kardashian, 37, during their flight back to Los Angeles on a private jet.

The couple’s daughter Penelope, 4, is sitting on Mom’s lap, doing her best to sing along, while their sons Mason, 7, and Reign, 2, can be seen in the background, sitting with family friends and nannies.

In November, PEOPLE reported that the duo are living together again.

At the time, a source told PEOPLE that Kardashian is still being “cautious” with her heart and “doesn’t want to say that they are back together until she knows for sure that Scott is fully committed to his family.

But so far so good, according to the insider: “Scott has been amazing to Kourtney, and she is very happy.”
