Hillary Clinton kicked off her 69th birthday with a sweet serenade from Stevie Wonder!

The music legend made a surprise appearance during Clinton's interview with The Breakfast Club on Wednesday, and after a little prodding from the radio show’s co-host, Wonder launched into his 1980 rendition of "Happy Birthday."

The 69-year-old musician wasn't shy about his admiration for the former Secretary of State. He showed up to the interview donning a black blazer with the words "1st woman president" and Clinton's name written on the sleeve.

"I'm really excited to be here and excited to support someone I have had such love and respect for for years," he explained.  "Truth be told, I think we as men have had our chance to work it out. It's time to let a woman do it."

As Wonder broke into the impromptu performance, Clinton swayed with the music, while the radio show's co-host clapped along.

Clinton has received lots of support from the music world, with Adele being the latest recording artist to publicly endorse the Democratic presidential nominee.

"I do know what to do — don't vote for him, that’s what I'm saying," Adele told the crowd of Clinton's opponent, Donald Trump during her concert in Miami on Tuesday.

Clinton attended the show, and tweeted the next day, "That was quite a birthday surprise, @Adele. Loved the show last night!"
