Kylie Jenner and her rumored boyfriend, rapper Tyga, spread some holiday cheer at the Children's Hospital in Los Angeles on Monday, but it's what the 17-year-old Keeping Up with the Kardashians star was wearing that has plenty of people talking.
The 25-year-old rapper was hosting LA Gear's Teen Impact Christmas Party for Pediatric Cancer patients. The two gave away Last Kings clothes, as well as gifts donated by LA Gear, Squishy Sand, Shimmer Jewelry Tattoos and 808 Audio headphones and speakers to patients who'll be spending their holidays in the hospital.

However, clad in tight gray skinny jeans, heels and a sports bra showing off her flat stomach, Kylie was certainly out to turn heads while doing good deeds.
The outfit also proved to be the perfect look for a butt selfie later that day.
Judging from her recent posts on Instagram, crop tops appear to be her winter top of choice.
Kylie recently took to Twitter to slam marriage and pregnancy rumors surrounding her and the Tyga.
