New York: Singer Justin Bieber is reportedly obsessed with popular augmented reality (AR) game Pokémon Go. The 22-year-old singer and his friends are big fans of the gaming app, which allows users to catch Pokémon in the real world, and managed to go largely unnoticed as they joined others on a Poké-hunt in Central Park here on Monday, reports femalefirst.co.uk. Bieber's friend Alfredo Flores posted a video of them on Instagram and wrote: "When Gyrados decides to pop up across the street from Central Park and all hell breaks loose!" Bieber's manager Scooter Braun also shared the video and wrote: "This is amazing. Justin Bieber and Alfredo Flores in New York City looking for Pokémon and no one looks at who is next to them".
