The trio reunited in a surprise performance at the Stellar Gospel Music Awards to sing Michelle's song, 'Say Yes'.
With all three dressed in white blazers, Beyoncé, Kelly and Michelle excited fans as they belted out the song.
The performance is expected to air in the US on 5 April.
In June last year, the girls briefly reunited when they filmed Michelle's music video for the same song.
The uptempo, feel-good track sees the trio unleash their dance moves as they celebrate with locals.
The music video was an iconic moment for the girls, as it marked 12 years since they released 'Bootylicious'.
"We're still loving each other and supporting each other," Michelle said at the time. "They have no idea what it means to me and I think it's full circle, we're still rocking it out."
Popular 90s group Destiny's Child last reunited on stage in 2013 at the Super Bowl.
