Luke Bryan calls sister’s sudden death 'tragic beyond words'

Luke Bryan is opening up about the difficult loss of his sister, Kelly Bryan Cheshire.

Kelly died in 2007 at the age of 39, and Luke has been fairly private about what happened to her.

But on Anderson Cooper’s “All There Is” podcast, the “American Idol” judge spoke more openly about her death.

"I never really explained what happened to my sister, there’s some misinformation out there on the internet and I think some people wonder what happened and they think that we’ve tried to cover it up,” he said.

He continued, "There is a very, very small percentage of people who die for no reason - and it’s called sudden death syndrome and that’s essentially what they described my sister’s death as."

Luke described his sister's passing as being "tragic beyond words".

"She was in her home doing her laundry and it was like somebody turned the switch off on her and it was just tragic beyond words."

Luke's older brother, Chris Bryan, died in a vehicle collision in 1996. However, he admitted that losing his sister was a different experience.

"My brother, you can conceptualize a car accident, but you can’t really conceptualize someone that was healthy as a horse and she’s just gone."

Meanwhile, Luke has heaped praise on his wife Caroline, observing that she's helped him to navigate some of the most difficult times in his life.

"I don't know anybody that could have done what she's done,” he said. "I mean, she goes into life thinking she's marrying a country music singer, and then next thing you know, she's helping the girls and the boys and still putting up with my antics.

The couple share sons Thomas, 17, and Tate, 15, and have been married since 2006.

Luke explained that Caroline had faced her own challenges, too, and he’s been ther

"She lost — her brother and [sister-in-law] lost a young seven-month-old baby [Brett]. And we've had to watch them deal with grief, losing a seven month old, very close to us and we love them."
