“Little drummer girl,” Kourtney Kardashian captioned the photos she posted to Instagram on Thursday (Dec. 16). Kourtney, 41, wasn’t naming her favorite gender-flipped Christmas tune – she was seated behind the drum kit of her boyfriend, Travis Barker. While Kourt didn’t share any videos of her playing the drums, she certainly got the poses down – which is half the battle, honestly. Even Travis, 46, approved, as he wrote out “Rockstar [drum emoji]” in the comments section.
