Beyoncé performed at the Stade de France as part of her Formation World Tour over the weekend, and one moment from the concert went viral; a young girl was spotted playing Pokémon Go on her phone as Beyoncé performed, and a few of her fellow show-goers in the front row were **t having it. The singer is expected to take the stage in Frankfurt, Germany, on Tuesday evening, so hopefully fans will be a bit more attentive.
