With Christmas less than a week away, Justin Bieber got in some last-minute shopping on Saturday (Dec. 20) at Toronto's Yorkdale Mall. While picking up presents for loved ones, the singer, who is back in Canada for the holidays, bumped into the handsome face of the mall's holiday campaign, Fashion Santa. "It's true! Celebs shop at #Yorkdale Can you #beliebe it?! @justinbieber + #yorkdalefashionsanta #yorkdalecheer," tweeted @YorkdaleStyle.

And while Justin causes a frenzy everywhere he goes, model Paul Mason (Fashion Santa) is quickly inheriting a cult following of his own. Aside from generally raising the bar on how our favourite holiday figurehead looks, he also poses for selfies with shoppers in the mall, helping to raise money for the Sick Kids Foundation, which supports Toronto's Hospital for Sick Children.

Posing in the likes of Burberry, Dolce & Gabbana and Givenchy, and having swapped a sack for a chic backpack, Paul has become an overnight viral sensation.

Justin tweeted that he has returned home for a "little R&R." The Stratford native has been on a whirlwind promotional tour for his album Purpose since its release on Nov. 13. When he wasn't busy taking over the small-screen with performances at the American Music Awards and The Voice finale, the 21-year-old was thrilling fans during intimate concerts, including a charity show in Toronto on Dec. 2.
