Beyonce and Rowland joined Williams for her planned appearance at the 30th Annual Stellar Gospel Music Awards to sing "Say Yes" -- a song that earned Williams a Stellar Award nomination. This was the ladies' first live performance since reuniting at the 2013 Super Bowl halftime show. The last time the women worked together was in June 2014, when Beyonce and Rowland appeared in Williams' "Say Yes" music video.
"Sometimes you just know when to show up," Williams said of Saturday's performance. "Last year they came on my song 'Say Yes' on my album Journey to Freedom. Then they agreed to do the video and I was like, 'We need to just do it one time together because it's one of their favorite songs.' It's so easy to just pick up the phone and say, 'Ya'll want to do it? Yes? Cool!'"
Despite some headlines speculating on possible rifts between the former group members, Williams told us that she and the girls are still like sisters.

"Friendship is the foundation of everything we do -- no drama," Williams said. "People are looking for drama but we have none to give you. It's literally friendship and sisterhood and respect."
Their sisterhood goes back to when the trio were practically kids and now they're raising children of their own. Beyonce had Blue Ivy on Jan. 7, 2012 and Rowland welcomed son Titan on Nov. 4, 2014.
"It is the absolute best. Titan has a laugh [that's] out of this world!" Williams said of Rowland's newborn. "I'm literally fiending to go see him just so I can see him laugh and smile. That's how contagious he is."
