Gladys Knight — The Secret White House Project

Gladys Knight is pulling double duty … “cause in between training sessions for “Dancing with the Stars,” our sources has learned Knight is also working on a top secret scripted TV show.

Sources close to production tell us … Knight has been cast to star in a show called “The First Family” … about a fictional President of the United States who”s juggling work with his family life. We”re told Gladys is playing the President”s mother.

Sources connected to Gladys tell our sources … the Motown legend is working extremely hard to handle both gigs … and producers on both shows are being very flexible to accommodate the star.

We”re told the sitcom is already garnering interest from a major network … which has made it clear they want to rush production to capitalize on Knight”s “Dancing” momentum.

We spoke with Byron Allen — the Executive Producer of “First Family” — who tells us, “Gladys is truly an American treasure and we”re excited to work with her.”
