In an interview with Yahoo Entertainment about the new film, which Holmes directed, the "Dawson's Creek" star said that her 16-year-old daughter sings "Blue Moon" during the credits and called her "very talented."
"I always want the highest level of talent," Holmes said. "So I asked her! She's very, very talented. She said she would do it and she recorded it, and I let her do her thing. That's the way I direct in general: It's like, 'This is what I think we all want -- go do your thing.'"
"Alone Together" isn't the first film in which Suri has showcased her voice. Holmes said that her daughter also sang in the film "Rare Objects," a period drama based on the novel by author Kathleen Tessaro, which Holmes also directed.
When Suri isn't busy making music, Holmes said her daughter enjoys just being a teen.
"She's a 16-year-old kid doing high school," Holmes said.
Holmes, who was 27 years old when she welcomed her daughter in 2006 with ex-husband Tom Cruise, doesn't often post photos of her daughter in order to keep her private life private.
In 2019, she spoke about "growing up" with her daughter in an interview with Elle UK.
"It's been nice that our ages fit," she said. "Every age that my child has been and my age at that time has been a good match. We kind of grew up together."
"Alone Together" is out now.
