Justin Timberlake, Michelle Obama and Others Pay Tribute to the Late Bill Withers

Legendary singer and songwriter Bill Withers died on Monday after suffering heart complications, according to his family. He was 81 years old.

Withers penned many classic songs through the 1970's and 80's including "Lean on Me", "Just the Two of Us", and "Ain't No Sunshine." He is survived by his wife and two children.

Meanwhile, tributes continue to pour in for Withers as of Saturday, including from notable celebrities. Singer Justin Timberlake called Withers his "biggest idol" in an Instagram post. "You taught me so much about how to keep it simple and real. I felt such a kinship with you even before we met. Your words and melodies... the chords that accompanied them... they reached into my soul and spoke to me so deeply. That's what your music did," he wrote. "You have always been one of the greatest and will forever be."

Radiohead's Thom Yorke tweeted Saturday: "Oh that voice ! Rest in Peace Bill Withers."

Eagles guitarist Joe Walsh told Rolling Stone about his longtime friendship with Withers and the singer's distaste for the business side of the music industry. "He was the greatest guy. I don't think he never really knew how many hearts he touched. I miss him already. It was an honor and a privilege to have been his friend," Walsh said.

Former First Lady Michelle Obama tweeted a tribute to the late singer. "Bill Withers made the sort of music that you couldn't help but sing along to—from 'Lean on Me' to 'Lovely Day,' he had a gift for giving voice to our joys and our sorrows. Truly one of the greats," she wrote. "Barack and I send love and prayers to his family and friends. He will be missed."

Former President Bill Clinton also wrote about Withers' messages of togetherness being important now more than ever. "Today as we mourn his death, we should lean into the sentiment of one of his most loved songs: lean on each other when times are tough and know that there's always tomorrow. May he rest in peace," he tweeted.

The band Portugal. The Man released a cover of "Lovely Day" as a tribute to the songwriter on Friday. "We grew up listening to AM radio in remote Alaska and Bill Withers was one of the mainstays on those long drives to the grocery store. Bill's music is imprinted in our DNA. It touches everything we do and we love him for the gifts he gave us. Bill will be missed but his music will live on forever," PTM wrote in the video's description.

Other musicians tweeted their remembrances of Withers, including R&B singer Ciara and songwriter Joseph Arthur.

Withers' music touched entertainers of all kinds. Actor Samuel L. Jackson and comedian Bill Burr also memorialized the singer on Twitter. "Thank you for some of the greatest music ever recorded," Burr wrote.
