Rihanna Steps Out in London, Gets Acoustic Treatment with Coldplay

She never seems to slow down, and earlier today (June 25) Rihanna was spotted leaving her hotel in London, England.

The “Russian Roulette” songstress went for a more casual look, sporting a grey tracksuit and half-up hairdo as she looked around with tired eyes.

Ri-Ri’s duet with Coldplay “Princess of China” just got the acoustic treatment, giving the song a whole new mellow flavor.

Back in September, Chris Martin told press that Rihanna was their obvious choice for the song- "So, in like a dream scenario, we had a song that I'd secretly kind of written to see if Rihanna would want to sing it."
