LeAnn Rimes is feeling blue after celebrating her anniversary in Mexico.

The singer shared on her Instagram Stories Wednesday that she’s canceling her upcoming shows in Spokane, Washington, and Seattle— scheduled for April 30 and May 1, respectively — because of health issues.

“Due to severe illness, I am unable to travel & perform this week,” she wrote.

She apologized for canceling the two shows but noted that they were being rescheduled to a month later.

“I am truly heartbroken to have to reschedule and I am so very grateful for your kindness, and continued support as I recover,” she wrote.

Rimes, 43, concluded, “I look forward to being back on stage and seeing you very soon.”

Last week, Rimes celebrated her 15th wedding anniversary with her husband, Eddie Cibrian, in Cabo. The couple tied the knot on April 22, 2011.

The “How Do I Live” singer posted pics and video from their romantic getaway on Instagram, while cryptically sharing they were dealing with serious issues at home — though she didn’t elaborate on what she was referring to.

“We got to step away for 3 days amidst work and some very tense, heart wrenching things happening at home with family,” she shared. “It’s been a different anniversary, one filled with tears and worry, but in between, there were moments of laughter and deep gratitude for this love of ours.”

‘”Day by day, we walk hand in hand through the rollercoaster of life… and god, i’m so grateful that it’s with each other,” she continued. “We’ve been through so much in our 15 years as husband and wife. we know how to ride the waves 🌊, hold each other in times of need, mend what needs mending.”

She also posted an anniversary message for her husband on Instagram, again hinting at dealing with health issues.

“15 years of loving you. 15 years of making memories. your love is such a gift. and, with all that’s taken place this year, i have new vows… in perimenopause and in health, with teeth and without… 😂,” she joked.

Last month, Rimes went viral due to a video self-care provider Human Garage shared of her sobbing uncontrollably while undergoing “deep jaw release therapy.”

Cibrian’s ex-wife, Brandi Glanville, later shaded Rimes for the emotional video, questioning, “I just don’t know why you share that.”
