Heart Cancels European Tour as Ann Wilson Must Have 'Time-Sensitive but Routine Medical Procedure'

Heart's Ann Wilson won't be able to take the stage for some time.

The sister duo, also featuring Nancy Wilson, announced their 2024 European summer tour is canceled, as Ann must "undergo a time-sensitive but routine medical procedure." However, she doesn't want fans to "worry" about her.

"We regret to inform you that all upcoming Heart performances in Europe are canceled," the band wrote on social media of the tour, which was set to span various countries from June 20 through July 12 with special guest Squeeze.

"In late May, Ann Wilson will undergo a time-sensitive but routine medical procedure for which the minimum recovery time is six weeks," added Heart.

The "Barracuda" group's statement continued, "Heart deeply regrets this unfortunate circumstance and hopes to return to Europe soon. Refunds will be available at point of purchase as applicable."

Ann, 73, then posted to her personal Instagram account and informed fans, "I'm okay! Please don't worry."

"I do apologize for any inconvenience this may cause," she continued. "It’s certainly an inconvenience for me. Love & respect always, Ann."

Heart recently wrapped a string of North American concerts that ran from April 20 through May 24. The band is scheduled to hit the road again with shows in the U.S. and Canada from July 30 through Dec. 15.

Last year, Ann spoke to PEOPLE about feeling as though her touring "stamina" was better than ever during an interview at the 6th annual Women Who Rock Benefit Concert presented by Gibson Gives. She also credited her youthful energy to having a more balanced lifestyle when it comes to alcohol.

"I'm not 100% sober. Usually, I have a glass of white wine after the show, but that's all it's down to now," she said at the time. "I got a really good handle on it. It's actually really good and it does help me with stamina and I do a really good warmup."
