Watch Justin Bieber & Jaden Smith Lose It When Kylie Jenner Performs 'Rise & Shine' Live For the First Time

Christmas came early on Friday night for a select group of folks when Kylie Jenner performed her viral "Rise and Shine" lullaby live.

Christmas came early on Friday night for a select group of folks attending a charity auction in Los Angeles when a famous friend convinced Kylie Jenner to perform her viral "Rise and Shine" lullaby live for the first time. The viral phenomenon blew up in October when Jenner sang the phrase to baby Stormi in a video, inspiring a cover version from Miley Cyrus and Cody Simpson. But it didn't get a live debut until Friday's benefit for LIFT Los Angeles and Inner-City Arts, according to the Huffington Post.   

After some prompting from Justin Bieber -- who performed a mini-acoustic set featuring "Never Say Never" and "Love Yourself" -- Jenner was convinced to get on the mic and sing the three-word phrase that she assured fans last month she was not trying to trademark or lockdown via cease and desist letters urging them to stop making their own "R&S" merch.

In a video of the performance, an all-white pants suit, Jenner casually approaches a microphone and sings the phrase, eliciting whoops from the crowd and inspiring Bieber to climb jump on Jaden Smith's back in glee.
