Justin Bieber is back from London, and on Wednesday he went shopping at Supreme skate shop in Hollywood. The pop superstar sported an ascot cap and oversized glasses, along with a pair of kicks that looked like they gave his 5'8" frame at least an extra inch.

When Biebs emerged from the shop, he traded in his green silk "Hotel CA" bomber jacket for a yellow hoodie, and after that he stopped for a slice of pizza at Tomato Pie Pizza Joint. Mmm, Biebs and pizza. Could there be a more delicious combination?

Sadly, Biebs still hasn't reactivated his Instagram account, and it doesn't look like he'll be doing so anytime soon. At his London concert the previous night, Biebs asked the audience, "Who thinks I should get my Instagram back?" But what he said next must have broken millions of hearts. After giving thousands of screaming fangirls hope that he might post some sexy new selfies in the near future, Biebs said, "Nah, I don't want to get my Instagram back... I'm sure... I think hell is Instagram. I'm 90 percent sure. We get sent to hell, we get like locked in the Instagram server."

WHAT?! Check out the video below, which was posted by a fan at the show at the O2 Arena on November 29:
