The Queen of Soul Aretha Franklin has withdrawn from two performances following health concerns, reported Reuters.

The two concert venues that were hosting Franklin's collaboration with the Chicago Symphony Orchestra on May 20 and a solo performance on May 26 made the announcement Monday.

"It was canceled for medical reasons," Dale Wolbrink, spokeswoman for Foxwoods Resort Casino in Connecticut, told Reuters. She did not disclose what the health issues were that caused Franklin to pull out of the shows.

According to the orchestra, Franklin, 71, canceled due to doctor's recommendations for treatment within the time frame of May 20 and 26.

In the meantime, R&B songstress Janelle Monae will be replacing Franklin's spot with the symphonic orchestra.

In 2010, Franklin was forced to cancel her entire tour to undergo surgery for reasons unknown.

The soul diva is known for her sensational 1960s "Respect" and "(You Make Me Feel Like) A Natural Woman," both lauded as one of the most memorable R&B hits at the time.

Franklin's June concerts are still expected to take place in Canada and Michigan.
