Justin Bieber Parties in London With Rihanna and Model Bronte Blampied While Sofia Richie Stays in Los Angeles

Justin Bieber partied in London, England with Rihanna -- and a blonde model who's not his rumored girlfriend, Sofia Richie, but a friend, Bronte Blampied. 

Ahead of Bieber and RiRi's separate, double-headlining sets at Virgin Media's V Festival this weekend, the trio hit trendy Tape nightclub on Friday night. Rihanna, 28, rocked a cleavage-baring denim ensemble, killer silver boots and dark glasses, while Bieber looked more casual in an over-sized white T-shirt and bleached, ripped denim jeans.

Inside the venue, fans took videos of the Canadian singer dancing, hanging out with the DJ, and spraying champagne.

Bieber and Blampied left the club together around 4 a.m., an hour that might have something to do with the reportedly disappointing show Bieber put on for fans at the festival the next night.

"I'm having the best night," he told the crowd of 75,000 people gathered in Hylands Park for night one of the festival. "Although I'm a little hungover."

According to a reviewer in The Telegraph, the show was mostly a dud. While there were "shimmers of [his] prodigious talent," Bieber was "lackadaisical and distant." 

None of that seemed to worry the 22-year-old pop star, however, as he tweeted out his thanks to fans in the audience."Thank you V Fest. Night one was real," he wrote.

On Sunday, Blampied caught a ride with Bieber in a private helicopter, flying from Battersea Heliport to the festival's second location in Staffordshire for his night two closing set.

Blampied has traveled with Biebs before. She was on his recent Hawaiian vacay, where she posted a photo to Instagram of the singer and friends on floating mattresses in the water. She is also reportedly a friend of Richie's.

While Bieber enjoyed his time in England, 17-year-old Richie kept busy in her hometown of Los Angeles, where she chopped her locks off and attended a Guns n' Roses show.
