"Happiness is a choice," says Michelle, who says she had to face her "repressed anger" issues to understand why she was depressed, clarifying that it all happened before Destiny's Child went their separate ways. "There were times in depression where I could stay in the bed all week -- but it's like, 'Girl, you've got to get up! Honey, get fabulous, curl your hair, put some lip gloss on it, do something -- you have to choose life!'"

Earlier this month, Destiny's Child (Williams, Beyonce and Kelly Rowland) announced that they're reuniting after eight years with some new music. Love Songs, out January 29, will be a collection of the trio's most romantic tracks over the years, in addition to at least one new song: Nuclear. Michelle is also working on a solo album that is described as an "inspirational" project.

The new Destiny's Child album release date coincides with the national tour kick-off of the Tony Award-winning Broadway musical Fela!, which is produced by Jay-Z, Will and Jada Pinkett Smith and Ruth and Stephen Hendel. In the production based on a true story, Michelle plays Sandra Isadore, an activist and the love interest of Afrobeat originator Fela Kuti, whose music and rousing lyrics openly attacked the corrupt military dictatorships that ruled Nigeria and much of Africa. The multi-city engagement kicks off at Shakespeare Theatre Company in Washington, DC and travels to Detroit, Chicago, Charlotte, Atlanta, Miami, Schenectady, Memphis, Dallas, Cleveland and Los Angeles.

As for Beyoncé’s alleged lip-synced performance of the national anthem at President Obama's Inauguration, Williams offers, "I will say this, it's not the first or the last time that someone has had to lip-sync…my greatest singer of all time, Whitney Houston, it came to light that her anthem was in fact lip-synced."
