Justin Bieber Pulled Off The Ultimate Dare to Live Surprise

And Rory Kramer's reaction was priceless

Justin Bieber has collaborated with videographer and close friend Rory Kramer through the years -- and the pop star was an unexpected guest at his old pal's Dare to Live premiere celebration (the series debuted last night on MTV).

"When your friend says he's not coming to your party...only to surprise you. @justinbieber (got your back til the day we die) @mtvdaretolive," Rory captioned the Instagram video above, which features the genuinely shocked Dare to Live frontman sharing a big ol' hug with Biebs. What a moment!

But Bieber wasn't Rory's only famous pal to mark the launch of the series: The Chainsmokers, Scooter Braun and Krewella also supported the adventure-seeker. Check out more photographs from the bash below -- and don't miss brand-new episodes of Dare to Live every Tuesday at 11/10c!
