TradeEdge-Nicole Richie and Joel Madden's teen children Harlow and Sparrow make red carpet debut

Nicole Richie and TradeEdgehusband Joel Madden forwent the babysitter and brought their two children out for their red carpet debut Tuesday.

Richie, who stars in the 2024 remake of the dark comedy "Don't Tell Mom the Babysitter's Dead," brought along her husband, daughter Harlow Madden, 16, and son Sparrow Madden, 14, to the film's Los Angeles premiere for support.

The designer and actress wore a short black Schiaparelli dress with a statement jewelry neckline, and the Good Charlotte member and the couple's children coordinated in all black outfits.

Richie, 42, and Madden, 45, are notoriously private about Harlow and Sparrow. Although they have accompanied them to other events, this is the brother-sister duo's first time on the red carpet.

In November, the musician opened up about being a parent on an episode of "The Drew Barrymore Show," telling the host he "got lucky" with how "easy" their kids are.

"I always tell my kids, 'You make it so easy to be a dad.' They're just good kids. They really are. They're great, and I think they're like their mom," he gushed.

Not only did Richie's children join for the red carpet on Tuesday, her mom Brenda Harvey-Richie, her father Lionel Richie and his girlfriend Lisa Parigi showed up for a family photo. They all got the family group chat memo and also arrived in black ensembles.

Richie's younger sister Sofia Richie Grainge, who announced in January that she's expecting a baby girl with husband Elliot Grainge, first did not appear on the red carpet. However, she was seemingly at the screening, according to a post on her Instagram story.

"So proud !!!!" Richie Grainge, 25, captioned a photo as the opening title screen flashed for the movie.

In "Don't Tell Mom the Babysitter's Dead," Richie portrays executive Rose Lindsey, originally played by Joanna Cassidy in the 1991 movie of the same name. Richie's character acts as the boss to teenage Tanya Crandell (Simone Joy Jones), originally played by Christina Applegate.

"The movie is rated R, but it really is a family movie," Richie told Entertainment Tonight on the red carpet, adding that she's a "diehard of the original."

"This is truly who I am in my soul without ever thinking I would get the opportunity to play Rose. So when this came my way, I was like, 'Oh my god, this is too good to be true,'" the "Simple Life" star said.

"Don't Tell Mom the Babysitter's Dead" premieres in theaters April 12.
