You've Never Seen a Justin Bieber Smile as Big as the One in His Selfie With Santa

When Justin Bieber dropped by the Yorkdale Shopping Centre in Toronto to presumably pick up some last-minute Christmas gifts on Saturday, the "Sorry" singer teamed up with the mall's "Fashion Santa" for one of the cutest holiday selfies you'll ever lay eyes on. The full-time silver fox and part-time trendy Santa Claus is actually a model named Paul Mason who poses for pictures in December with mall-goers in support of the Sick Kids Foundation, an organization that raises money for Toronto's Hospital For Sick Children. If Justin's ear-to-ear grin is any indication, the pop star was extremely psyched to meet him. See the snap below, and then check out some other adorable celebrity Christmas cards!

It's true! Celebs shop at #Yorkdale! Can you #beliebe it?! @justinbieber + #YorkdaleFashionSanta 😍🎅 #YorkdaleCheer
