We're not so sure how to feel about this...
Overseas Beliebers must be SO happy their main man is back over the pond!
Check out a pic of JB (above) with one lucky fan earlier today! Ha!
Uh oh! Gotta keep an eye out for Selen-er! LOLz!
Gearing up for the event, Bieber tweeted:
I LOVE PANDEMONIUM!! I LOVE MY FANS!! I LOVE MY BELIEBERS! #BOOKSIGNING :)
The fans definitely came out in DROVES (below)… poor Justin's hands will probably fall off after signing all those autographs!
Don't get TOO crazy now, you Beliebers!
