We have no idea whether Abel Tesfaye, aka the Weeknd, would be down for working with Bieber. But, Weeknd is one of the hottest names in R&B at the moment, thanks to Tesfaye's acclaimed mixtapes and collaborations with Drake on 'Take Care.’ The Weeknd also has a Lady Gaga remix to his credit. And he's from Toronto, and we know that Bieber likes to work with and support fellow Canadians – just ask Drake and Carly Rae Jepsen!
