Country music star Luke Bryan thanked his fans for their prayers after revealing that his baby niece, Sadie Brett Boyer, passed away on Tuesday.

LUKE BRYAN THANKS FANS FOR PRAYERS AFTER NIECE DIES

Boyer, born in summer 2016, had been suffering from an undisclosed heart condition. The baby was the daughter of Bryan’s wife Caroline‘s brother Bo Boyer and his wife Ellen Boyer.

“We thank all of you for your prayers,” tweeted Bryan. “Love y’all.” The family kept mostly quiet about Sadie’s struggles, aside from Bryan posting a few updates over several months to his app.

The Bryan family has been struck with tragedy multiple times, with Luke’s brother Chris dying in a car accident at age 26. His sister Kelly died unexpectedly in 2007 at age 39, and then her husband Ben Lee Christine followed suit in 2014. Bryan and Caroline took in their child Til at that time.

Luke is currently in the midst of his Kill The Lights tour, which kicked off Feb. 17, and will be hosting the Academy of Country Music Awards with fellow country singer Dierks Bentley on April 2.
