The Biebs tossed her right into that cold water! Ouch!

Sofia Richie looked pretty downcast at the Adele concert over the weekend, and it's probably because Justin Bieber is running around London having a fling with model Bronte Blampied. Where does he even meet these chicks?! Its gotta sting, considering poor Sofia was just with him in Japan earlier this month and totally acting like his new girlfriend.

JB loves 'em and leaves 'em quicker than anyone in Hollywood! The "Sorry" crooner was spotted with his new British beauty at Tape nightclub on Sunday, just two days after they made their first appearance together at the same venue.

Perhaps Lionel Richie's daughter could call Selena Gomez or Hailey Baldwin and get some tips about coping with this heartache?
