Justin Bieber and superstar pal Jaden Smith went on a shopping spree at Hamleys in London ... known to carry some of the finest toys in the world. Would you expect these young millionaires to shop anywhere else?

Biebs couldn't wait to jump on his cell phone as soon as he left the store. Perhaps the 16-year-old singer was checking with mom to see if it was okay to drop all that money on toys.

Jaden, rockin' a Chicago Bulls cap, kept a firm grip on his blue purchase while the two made their way through the crowd of screaming fans. Will Smith's son is hanging in London while his little sister Willow performs as the opening act on Bieber's tour.

Biebs was recently honored with a lifelike statue of himself made of wax. See his waxy twin ... after the jump.
