Barbra Streisand relies on her son's opinion when choosing what movies to star in.
The 70-year-old actress is mother to 45-year-old actor and writer Jason Gould, whom she shares with former husband Elliott Gould.
Barbra stars in new comedy The Guilt Trip, in which she plays an overprotective mother to co-star Seth Rogen.
Barbra is very close with her own son Jason and values his advice.
After reading the script and giving his approval, Barbra was happy to take on her role in The Guilt Trip.
"He said, 'Ma, I think you should do it.' " she told Extra.
Screenwriter Dan Fogelman is elated that Barbra decided to join the cast.
Apparently his late mother, who unfortunately perished from cancer before the film was shot, was one of Barbra's biggest fans.
"My mom would be a woman on fire right now," Dan said.
"She would be chasing down Barbra Streisand right now, probably get kicked out of this premiere. I'm really proud of the movie."
The Guilt Trip is released in US theatres this week.
