Destiny's Child Reunion Performance - Beyoncé Joins Kelly and Michelle at Stellar Awards

Beyoncé has been working overtime lately. Just days after news of a new shoe collaboration with celebrated designer, Giuseppe Zanotti, hit the net, the pop star teamed up with former band mates, Kelly Rowland and Michelle Williams, for a Destiny's Child surprise reunion performance at the Stellar Awards.

The three previously collaborated on the studio version of Williams' gospel song, "Say Yes," an EDM-inspired remix of Nigerian gospel song "When Jesus Says Yes." The song was nominated for three Stellar Awards, including Urban/Inspiration Single of the Year, Music Video of the Year, and Female Vocalist of the Year.

At the time of its recording, the single was the first time that the three Destiny's Child members had sang together since Beyoncé's 2013 Super Bowl XLVII halftime show performance.

According to Williams, the song "Say Yes" happened accidentally. "They received an advance copy of the album and called, saying, 'We love 'When Jesus Says Yes'...there has to be a Destiny's Child mix of the song,'"

The trio also filmed the music video together.

"It was so much fun. It was like we were little kids again," Williams said of working on the video with Beyoncé and Rowland. "I have their back and they have mine. They have showed themselves to be loyal to me time after time. They have proven they are my sisters time and time again."

Neither Williams nor Destiny's Child were listed as scheduled performers during the ceremony, so the audience was quite surprised at their high-profile treat. The show doesn't air until April 5, but fan-generated snippets of the performance made the rounds on Instagram.

As for those rumors of a Destiny's Child reunion tour? A rep for Beyoncé told Billboard that they're "completely false."

"There is absolutely no tour," the rep says.

The news makes sense, though; as Beyoncé is slated to star in the upcoming Bradley Cooper-directed film, A Star Is Born. By starring in the remake, she'll join the ranks of Janet Gaynor and Judy Garland -- both actresses who previously received Oscar nominates for their starring roles in the film.

"Beyoncé feels this could be her big Hollywood breakthrough," a movie insider told The Daily Mail. "It's a role she has wanted for years. She's shown that she can act in Austin Powers: Goldmember, and held her own singing in Dreamgirls, but this is her chance to prove her dramatic range and maybe even win an Academy Award.'
