Grace Gummer has two sisters and an elder brother
The daughter of Oscar-winning actress Meryl Streep is to make her screen debut playing the child of a celebrity couple in a new US TV series.
Grace Gummer will appear in Gigantic, a new series for Nickelodeon channel TeenNick due to screen in early 2010.
The 23-year-old - who will play a teenage girl in the show - appeared on the New York stage last year.
Gummer is the third of Streep's four children with her husband, sculptor Don Gummer, who the star married in 1978.
Grace's sister Mamie, 26, had a small role in film Taking Woodstock and also appeared in TV series John Adams.
But Streep has largely kept her children out of the limelight.
Nickelodeon's Marjorie Cohn said the new series would appeal to its audience because "they love celebrity and pop culture".
