Audra McDonald

Departing Private Practice star Audra McDonald is heading back to Broadway.

The four-time Tony winner will star in a new production of the George Gershwin and DuBose Heyward opera Porgy and Bess at the American Repertory Theater production in September, she told Playbill.com.

"I'm looking forward to it. I feel like I'm old enough [to play Bess]," McDonald said.

The new production is a re-imagining of the classic opera, which follows Porgy, a disabled beggar, and his love for Bess.
