It’s a family affair.

Gwyneth Paltrow’s son, Moses, made his red carpet debut to support his mom at the “Marty Supreme” premiere in Los Angeles Monday.

The mother-son duo shared a few laughs as they placed their arms around each other to pose for photos at the Samuel Goldwyn Theater.

The “Iron Man” actress, 53, stunned in a strapless black gown from her label, Gwyn, while Moses, 19, rocked a brown-and-black suede sweater with brown pants and shoes.

Paltrow was also joined by her husband, Brad Falchuk, on the red carpet.

The TV producer, 54, wore a white button-up shirt and brown tie, a black blazer, gray slacks and brown shoes for the outing.

The Goop founder shares Moses and daughter Apple, 21 ,with her ex-husband, Chris Martin, with whom Paltrow was married from 2003 to 2016.
