One of Bieber's best-known endorsement deals was with Calvin Klein. His 2016 partnership reportedly gave the brand a boost in sales and social-media followers.
Prior to that, in 2010, the singer struck a deal with Proactiv, and the following year, he had a successful collaboration with Nicole by OPI nail polish.
Additionally, Bieber has had deals with major brands like Adidas, Beats by Dre, Best Buy, T-Mobile, Schmidt's, and Vespa.
