Are the girls of Destiny's Child reuniting for a third time? Not exactly.

Michelle Williams, Beyonce Knowles and Kelly Rowland reunited for Williams' new gospel song and music video, "Say Yes," a track off her upcoming fourth solo studio album, "Journey to Freedom". In the video, Williams takes the spotlight, dancing and singing in front of a group of Caribbean dancers waving their flags.

Beyonce sings and dances in a garden while wearing denim shorts, a long white poncho and a huge gold neckpiece. Rowland, who is rumored to be pregnant with her first child, does the same while sporting a short haircut and a white crop top.

The video ends with the trio performing a traditional African-inspired dance surrounded fans and musicians, before moving in for a group hug. Williams debuted her new video on a segment on ABC's "Good Morning America".

"This song is so inspiring, and there's not enough music out there like this, and I'm proud to be a part of it," Beyonce said in a behind-the-scenes video. Rowland called Williams' new song "infectious" and added that "the world needs to hear it."

"Working together with Destiny's Child again was amazing," Williams said today live on "Good Morning America". "I am just so moved by this moment right now and to have my girls on there. Sometimes the director or production assistants had to say like, 'OK, girls, bring it back home. Bring it back together,' because when we were together, we go back to how we were when we were younger, just always laughing and talking about things. It's been a great moment."

She explained that the album is about her "personal journey to freedom."

"Freedom from what was probably keeping me from being my best. It could have been bad relationships, business and personal wise. Not feeling all the way confident within myself," Williams explained on GMA. "It's about breaking "free from whatever it is that's keeping you from being the best person you can be."

This is the first time the former group members sang together since their 2013 Super Bowl performance, when Williams and Rowland joined Beyonce on stage for her half-time show.

"Journey to Freedom" is due out Sept. 9 in North America.
