'Voice' Coach Blake Shelton Mourns the Death of Songwriter-Producer and Personal Friend Busbee

Blake is heartbroken about the loss of his dear friend Busbee. Busbee lost his life over the weekend to a yet-to-be-disclosed illness.

It was a black Sunday for Blake and the whole music industry, as the death of Busbee, born Michael James Ryan was made public.

Blake wrote of his heartbreak via a tweet on Monday morning stating how devastated he and Gwen felt at a loss, as reported by PopCulture.

He wrote:

"I absolutely can't accept the loss of mine and Gwen's friend Michael (Busbee)...Too much to say for social media."

He stated the pain and "unfairness" of it all and how faith was the only way he would find peace, just like Busbee had when he was alive.

Also, on Monday evening Blake tweeted a picture which featured a laughing Gwen seated on Blake's laps on a sofa, with Busbee seated beside them, looking jolly.

The caption of the photo was equally sad as Shelton said he couldn't stop thinking about his friend.

The level of relationship between the trio was glaring as he co-wrote "Every Goodbye" on Blake's album "If I am Honest." He also produced Gwen Stefani's album "You Make It Feel Like Christmas."

Our hearts go out to Blake and Gwen as they mourn the passing of the 43-year old producer.

According to the Washington Post, the news of the painful exit of the Grammy-nominated songwriter was announced by his music producer, Warner Chappell on September 29.

Busbee's cause of death, however, hasn't been publicized. However, Variety reports that Busbee was being treated for Glioblastoma, a kind of brain cancer before his demise.

Busbee, who was born in Walnut Creek, California, wrote and produced a lot of songs that we will forever find groovy.

He worked with famous artists like Katy Perry, Pink, Keith Urban, and Carrie Underwood, among many others.

"My Church" a single by Maren Morris which was co-written by Busbee, was nominated for the best country song at the Grammys.

Tributes have been flooding the internet as the world would miss such an icon.

We agree with the sentiments of "The Voice" coach. Busbee will surely be missed.
