Rihanna okay after emergency trip to hospital Monday night

(HMG) – Rihanna was rushed to the hospital on Monday night after playing a sold-out concert in Zurich, Switzerland!

RiRi was taken to the Hirslanden private clinic around midnight for an “unknown condition”, but was released just before 3 am.

Reps for the hospital have confirmed that Rihanna was at their emergency room Monday night but “do not know the details.”

Sounds like it wasn’t anything too serious as RiRi was able to perform last night in Lyon, France.
