Destiny's Child reunites in Michelle Williams' 'Say Yes' video

LOS ANGELES -- Michelle Williams reunited (briefly) with her fellow Destiny's Child members Beyonce and Kelly Rowland for her new song "Say Yes."

The catchy track, which also features vocals by Beyonce and Rowland, is off Williams' upcoming album "Journey to Freedom," which is due out on Sept. 9. The music video for "Say Yes" features Williams, Beyonce and Rowland dancing together like old times.

"Working together with Destiny's Child again was amazing," Williams said on "Good Morning America" on Wednesday. "I am just so moved by this moment right now and to have my girls on there."

Williams also said the ladies had a great time on set together and might've goofed around a little too much.

"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," the 33-year-old singer said.

In a behind-the-scenes video from the shoot, Beyonce said, "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."
