Justin Bieber parties with mystery blonde

Justin Bieber was spotted leaving a London nightclub with a mystery girl in the early hours of Saturday (20.08.16) morning. The 22-year-old singer - who is reportedly dating Sofia Richie, 17 - was spotted partying with Rihanna at Tape nightclub in the English capital before leaving the venue with a blonde female just before 4am. Justin and Rihanna are in the UK to play V Festival this weekend and it was previously revealed that Justin will be soaked with 800 gallons of perfectly purified water during his performance. The 'Never Say Never' hitmaker will take to the stage on Saturday at the music extravaganza's Chelmsford venue, Hylands Park, in south east England and then travel to Weston Park, Staffordshire, West Midlands, for his headline set the next day. Justin's set is said to be the most challenging production the festival has ever seen in its 21-year history. He has requested the water to be 40 degrees when it is fired at him on stage. Rihanna, 28, will also headline the Virgin Media Stage over the August weekend, performing on opposite nights to Justin. Sia will play at the same venues and on the same dates as Justin, as will Bastille, Jess Glynne, James Morrison, Joe Jonas' pop rock band DNCE, Halsey and Mike Posner. David Guetta will be at Weston Park on Saturday before heading over to Hylands Park for Sunday. He will play on the Virgin Media Stage on the same days as Little Mix, Years & Years, Travis, All Saints, Example and Bebe Rexha.
