Hazel Moder has officially made her red carpet debut!

Julia Roberts' 16-year-old daughter attended the premiere of Flag Day during the 74th Cannes Film Festival in Cannes, France, looking adorable as she posed on the red carpet alongside her father, Danny Moder. Julia and Danny are also parents to Hazel's twin brother, Phinnaeus, and 14-year-old son Henry.

Hazel went '90s chic in a butterscotch yellow button-up lace shirtdress with black Mary Janes, while Danny sported a classic black tux to promote his cinematography work on Flag Day, a film featuring Katheryn Winnick, Sean Penn, Regina King, Josh Brolin and more.

Hazel and Danny weren't the only ones having a father-daughter moment on the red carpet, however. Sean Penn brought his 30-year-old daughter, Dylan Penn, to the same event, and she certainly didn't hold back with the glam. Dylan dressed to impress in a beautiful strapless Chanel gown with an embroidered belt and strappy black heels.

The two were also joined by 27-year-old Hopper Penn, who matched his dad in a classy black suit. "Last night was a dream," Dylan later raved on Instagram. "Thank you to everyone who made this possible! I am forever grateful."

"A dream come true to attend my first Cannes Red carpet with my @diormakeup family," Iris wrote on Instagram. "~* this dress @mariagraziachiuri wow."
