Just a week ago, Justin Bieber seemed to be heating up with Sofia Richie, but could there already be a new girl in his life?
The pop star spent the weekend in the U.K. with aspiring model Bronte Blampied, who also hung out with his group during a recent vacation in Hawaii (where he was rumored to be hooking up with Sahara Ray).
"Every night, she went back to his luxury apartment," says a source of Bieber, 22, and Blampied. "They looked like a couple, and she stayed over at his place."

Although there was no PDA while they were out and about, "she was with him the whole weekend and never left his side," says the source.
The pair partied on Friday at Tape night club and stayed in Saturday night after visiting a spa together and attending the V festival, where Bieber performed.
Last week, Bieber traveled to Japan for his Purpose World Tour with Richie, 17, and the pair were photographed holding hands and kissing in a park.
However, a source told PEOPLE "it's virtually impossible where he's at in his life and career for anything to last with these girls. He's not settling down."
