Bieber and his 20 friends have a 10,000 pound budget for the night and had been looking out the perfect London venue over the past few weeks, reported Daily Mirror.
Last year, the 'Baby' hitmaker was given a 65,000 pound Fisker Karma car as a birthday gift by manager Scooter Braun.
"Justin wants to celebrate in style and he loves clubbing in London. It's no accident that there's a break in his UK tour which coincides with his birthday. He's been looking for the perfect venue and finally settled on Cirque Du Soir as he loves the kitsch theme. The venue is all ready for him, with clowns, goblins, aerial acts and some fire-eaters," a source said.
