Rhianna spent $21,000 a night on a hotel room.

The plush living quarters boasted three kitchens, four bathrooms and a private gym, as well as four terraces overlooking the city.

One thing Rihanna won't have been doing in her suite is playing Pokemon Go.

The 28-year-old beauty recently warned her fans at a gig in France that she didn't want them whipping out their phones to text their loved ones or play the smash-hit Nintendo smartphone game.

She told the audience: "I don't want to see you texting your boyfriends or your girlfriends. I don't want to see you catching any Pokemons up in this bitch."

Rihanna hasn't been afraid to splash the cash during her world tour.

In May, she spent a reported $15,000 at strip club V Live in Houston, Texas, hours after performing at the city's Toyota Center.

The Bajan beauty headed to the night spot with her opening act, 24-year-old hip hop star Travis Scott.

A video posted online appeared to show Rihanna with a handful of cash while standing next to a scantily-clad dancer.

But it wasn't the first time the raven-haired stunner has splashed out big money in the V Live strip club.

In November 2013, the star and her on/off boyfriend Drake dropped $17,000 between them in the night spot after he had performed at the Toyota Center.

According to reports at the time, Drake, 29, splashed out $12,000 and Rihanna spent around $5,000 in the club, where they sat side-by-side and were said to have been very "touchy-feely".
