Kylie Jenner turned the big 2-0 today, but instead of gifting herself with some birthday presents, she’s giving back.

In the video, Kylie and Harry start off by laughing over “How old” Kylie is today, but things take a more serious tone as Harry asked, “Did you know every hour a teen in the U.S. gets diagnosed with cancer?”.

“Thank you Harry and Teen Cancer America for giving me this opportunity to help give back,” Kylie added.

Kylie mentioned the charitable act during an interview with E! News earlier this week.

“I’m doing special charity things on my birthday and I like sentimental things, because the materialistic things, if I want something, I’ll usually get it myself,” she revealed at the time.

Khloe Kardashian decided to use her app to share an adorable video montage for Kylie, promoting it on Twitter.

“Happy birthday to my baby,” she wrote, tagging the birthday girl.
