Wife Shannon Tweed-Simmons confirmed the news with a picture of the offending calcium oxalate buildup.
Some good news for the Kiss nation: Gene Simmons is on the mend. The legendary singer/bassist for the greasepaint rockers is resting comfortably after undergoing surgery to remove kidney stones, according to a series of posts from wife Shannon Tweed-Simmons. "Well, now that the cats out of the bag, this is Gene’s second of three procedures that will remove these large kidney stones so he can move on with Rockin’ & Rollin'," she wrote on Tuesday (Oct. 1) in a tweet that included a link to an Instagram shot of an ultrasound of what appeared to be one of the stones.

Kiss postponed a concert in Salt Lake City in September after Simmons said he had to fly home for an unspecified medical procedure, calling it "nothing serious… but it must be taken care of now." The show was the final slated U.S. performance on the band's End of the Road world tour before they are slated to move on to a November swing in Australia. The group also postponed shows in Los Angeles and Oakland last month due to "unforeseen scheduling issues," with the gigs re-scheduled, respectively, for March 4, 2020, and March 6.
In addition to wishing her longtime love a happy anniversary, Tweed-Simmons also posted a picture of an annoyed-looking Simmons sitting in a wheelchair in a hospital corridor while "stealing socks." A spokesperson for Kiss could not be reached for comment on the posts or further information on Simmons' condition.
