Julia Roberts' 16-year-old daughter made her red-carpet debut with her dad at Cannes

• Julia Roberts' teenage daughter Hazel made her red carpet debut at the Cannes Film Festival.
• The "Pretty Woman" actress has three children with cinematographer Daniel Moder.
• They welcomed twins Hazel and Phinnaeus in 2004, and son Henry in 2007.

Julia Roberts' teenage daughter made her red-carpet debut at the Cannes Film Festival on Saturday.

Sixteen-year-old Hazel joined her dad, cinematographer Daniel Moder, at the festival premiere of "Flag Day," a drama starring (and directed by) Sean Penn that also features his daughter, Dylan Frances Penn, in a lead role. Moder was the film's cinematographer.

Walking the red carpet at the premiere, Hazel wore a long yellow button-up dress and black Mary-Janes, while Moder donned a classic black suit for the occasion.

Moder and Roberts met on the set of the 2001 adventure film "The Mexican."

Although the two were both dating other people when they first met in 2000, they eventually reconnected and got married at Roberts' New Mexico ranch in 2002. The couple has three children together: twins Hazel and Phinnaeus, born in 2004, and son Henry, born in 2007.

Despite having one of most famous mothers in Hollywood, Roberts' children with Moder have remained largely out of the spotlight for most of their lives. According to Today, the family had previously all posed for photos together back in 2015, at a private event in Malibu, California.
