Britney Spears is addicted to Pokémon Go.

Speaking on 'Rove and Sam' on Australia's 2DayFM, she said: "We do that a lot.

"[My kids] are addicted to it, they're constantly talking about it, and I'm introduced to these new Pokémon everyday.

"They got me to go shopping all over the mall to look for Pokémons. I was like, 'Well you know what, it's summer we have nothing to do today, let's go look for Pokémon!'"

Britney is not the only star to become obsessed with the game, Justin Bieber recently joined dozens of other people in New York's Central Park as they tried to catch a rare Pokémon.

His manager Scooter Braun posted a video of Justin as he ran into a huge swarm of people and everyone could be heard yelling about the rare Gyarados creature as they tried to capture him.

Scooter wrote: "This is amazing. @justinbieber and @alfredoflores in nyc looking for Pokémon and no one looks at who is next to them. (sic)"

He finished the post with lots of crying laughing emojis.

John Mayer recently spent $99.99 for 14,500 PokeCoins, while Tyga was spotted ignoring girlfriend Kylie Jenner as he checked for Pokémon at Budapest airport.

And Lily Allen revealed how she had become obsessed with it and had even been hunting for them at the Church of Scientology Celebrity Center in Hollywood.

Lily has been sharing her new passion with her fans on her Twitter page, keeping them up-to-date with her progress with the Pokémon.

The mum-of-two said the game was "pure escapism".
