It's a whole family musical!
Kourtney Kardashian, Scott Disick, and their kids took to the skies this week — and the musical family even broke out in a rendition of "Twinkle, Twinkle, Little Star" while onboard their private jet.
The duo just returned from a skiing trip in Aspen with kids Mason, 7, Penelope, 4, Reign, 2, and a host of friends. Scott, 33, took to Instagram to show off the group's vocal performance while traveling.
The couple — who previously split in October 2015 but recently reunited — are now rumored to be expecting Baby No. 4 together.
"Kourtney never stopped loving him, and they both feel they make great babies together," a source revealed. "Having another child with Scott will be a dream come true."
