Rihanna warns her fans not to 'catch any Pokemons up in this b***h' at concert...as she shares racy bikini snap on Instagram

Rihanna displayed her feminine side when she posted a seductive bikini snapshot on Monday.

But the 28-year-old singer's Instagram username is BadGalRiri for a reason when she brought out her feisty traits during the European leg of her tour.

'I don't want to see you catching any Pokémons up in this b***h,' the pop singer warned attendees at a recent concert.
