*Jennifer Hudson’s son David is set to make his film debut in his mother’s upcoming holiday movie musical “Black Nativity.”

The Oscar winner plays a single mom in the retelling of the Nativity story with an all-black cast. David, her 3-year-old with fiancé David Otunga, will make a cameo.

“He put himself in the film as one of the extras,” she tells USA Today. “He is a little industry baby. He sits in the director’s chair and puts on the headphones.”

The “Dreamgirls” star admits she had a blast making the film, in which Forest Whitaker and Angela Bassett play her parents.

“I love them so much. I looked up to them as a kid. And now that they are my mom and dad – that’s too much,” she said.
