This new Pokémon GO craze is all good, clean fun - but you know that things are getting out of hand when people are more interested in a game on their phones than what's happening in front of them.

Last week, someone in the front row of Beyoncé's gig in Paris was spotted playing the mobile game instead of paying attention to what was on stage (watch that clip below) - but it seems that Rihanna will not tolerate any of that sort of behaviour at her gigs.

She was filmed by a fan at her gig in France the other night warning the crowd: "I don't want to see you texting your boyfriends or your girlfriends. I don't want to see you catching any Pokémons up in this bitch."

Only recently, Slipknot frontman Corey Taylor was caught on camera slapping a phone out of a fan's hand - although that was before Pokémon GO was released.

What do you think - is it right or wrong to dictate what your fans do at your gig once they've paid to see you?
