Justin Bieber poses for selfie with Fashion Santa

Justin Bieber graced Toronto's Yorkdale Shopping Centre with his presence and naturally, his shopping trip wasn't complete without a Fashion Santa selfie.

The pop star posed with the world's most stylish St. Nick and Yorkdale uploaded the photo to its Instagram feed. Naturally, the internet went nuts.

Fashion Santa - i.e. model Paul Mason - has gained international attention over the past few weeks for his contemporary spin on Father Christmas.

Instead of living it up in the North Pole, Mason hangs out by Yorkdale's Harry Rosen and takes selfies. For each one uploaded to social media with the hashtag #YorkdaleFashionSanta, the mall donates $1 to the SickKids Foundation, up to a total of $10,000.

If you want to see Fashion Santa, you'll have to hurry because he's making his last appearance on Wednesday, December 23 from 12 p.m. to 8 p.m.
