Some of music's biggest names have defended Beyonce's possible lip-sync at the presidential inauguration. Aretha Franklin says she "really laughed" at the whole thing and now one of the people closest to Beyonce, a fellow Destiny's Child member, says folks should let this go.

"It's disappointing and saddening to me," Michelle Williams said today on " Good Morning America" of the controversy that exploded in the press after members of the U.S. Marine Corps Band insinuated the pop icon may not have belted out the anthem live. "It's just shocking to me that it's taken on this."

"I love her so much. I know what she possesses," Williams, 32, said. "That was such a big moment for her and I just wish people would just let it go and just continue to look for what she's going to be bringing for ya'll in the future."

That future, for Beyonce, includes headlining the halftime show at next month's Super Bowl in New Orleans, where she reportedly jetted immediately after her inauguration performance to continue rehearsals.

While it has been heavily rumored, and anticipated, that Williams and Destiny's Child's third member, Kelly Rowland, would be joining Beyonce for the halftime show, Williams is staying mum.

"I wish that I could say it's possible," she said. "I wish that I could say and I know that you all showed some 'Fela!' rehearsals so that's what I've been doing and what I've been focusing on."

She did have more to say, however, about the group's compilation album, reportedly set to drop on Jan. 29. The album will feature a new song, "Nuclear," as well as previously released hits.

"It just showcases where we left off from but it feels like we never left," she said. "The vocals are just beautiful. I had a chance to put my two cents in the song ["Nuclear"]and I'm just so happy that we had that moment again."

What Williams is focusing on now, however, is her return to the Broadway stage in a 16-city tour of "Fela!", the Tony-nominated musical about the life of Nigerian activist and singer Fela Kuti.

"I'm so excited to have this opportunity," she said of playing Sandra Isadora, Kuti's African-American lover, in the tour, opening next week in Washington, D.C.

After the Destiny's Child trio took time off to focus on their solo careers, Williams became a frequent face on Broadway and released two gospel recordings and a chart-topping dance-pop album.

Williams made headlines earlier this month when she revealed she had suffered from moderate depression since the age of 15 or 16. She told the Associated Press she has been able to manage it through exercise, therapy and positive thinking.

"When I brought that up it wasn't planned, it wasn't strategic. I didn't plan on telling that," she said on "GMA," confirming she has created the Michelle T. Williams Foundation to help others struggling with the disease.

"I just want people to know that it's okay to go talk to somebody," she said. "It's okay to go get some help. It's really okay to deal with whatever it is that had you so low. I choose to be happy. It is a choice. I choose life and God has blessed me with a great one."
