Ludacris promises ‘a lot of tears’ on YouTube music series

Ludacris is hoping the new music competition series he’s hosting on YouTube will take an aspiring artist and “catapult them to superstardom.”

The “Vitamin D” rapper is host of “Best.Cover.Ever,” which pairs budding musicians with established stars for a shot at performing a duet on the online giant. The 10-episode series debuts Nov. 20.

The series stars Demi Lovato, Katy Perry, Keith Urban, Jason Derulo, Charlie Puth, the Backstreet Boys, Flo Rida, Nicky Jam, DNCE and Bebe Rexha.

During each roughly 30-minute episode, the music stars pick two artists who best covered one of their songs from hundreds of video submissions and invites them to Los Angeles for a chance to sing with their idol.
