Rock group KISS member Gene Simmons updated fans on his health condition after he became weak onstage and had to continue his performance sitting down due to dehydration.

The 73-year-old musician was performing in Brazil with his legendary band when he announced he had to take a breather in the middle of the concert. 

"Ok, kids. Not a big deal. Thanks for your kind wishes. Last night we played Amazon jungle Stadium/Brazil. Humidity and temperature were sky high," Simmons reassured his fans on Twitter.

"I was dehydrated and was forced to sit for a song. We got back on stage in 5 minutes & finished the show."
