Justin Bieber spent the weekend babysitting and crowd-pleasing.
As previously reported, the artist spent time in the pool with Mason Dash Disick on Saturday afternoon, prior to jumping on stage in Miami that night with Ariana Grande.
The beloved singer joined his fellow star on her Honeymoon Tour, planning to to perform a duet of "Love Me Harder," only Justin forgot the lyrics!
"So I feel bad, I forgot the words Ariana," Bieber told Grande while performing inside the American Airlines Arena. "I've been trying to memorize them backstage for like an hour!"
Despite this faux pas, the tandem perform two tracks together, i including Bieber's hits "All That Matters" and "As Long As You Love Me," with Grande taking over the rap verse originally performed by her boyfriend Big Sean.
Back in August 2013, when Grande was first making a name for herself, she received a kiss on the cheek from Bieber, prompting an unfortunate flurry of negative online activity from Justin's loyal fans.
But everyone now knows Justin and Ariana are simply good friends.
"Thank you @ArianaGrande and thank you Miami," Bieber Tweeted after the performance. "I missed the stage. See u soon."
It's true: Bieber will be returning to the music scene in the very near future.
Grande, meanwhile, added in response: "Thank u Miami babes and thank u @JustinBieber!!!"
