"My mom has helped me so much," Leon, 19, says in an exclusive clip. "She has great style and she's an amazing dresser."
The mother-daughter duo admire each other's fashion sense so much that they have a clothing line together called Material Girl, but Leon went solo to become the face of Pop.
Leon's decision to do the ad might have to do with her mom's close relationship with the designer. McCartney shared a preview of the campaign in an Instagram picture posted in March, writing, "Lola, who I've known her entire life, is at the beginning of her career as a performance artist. She's an independent, inspirational and free-spirited young woman. Despite being born in the spotlight, she has kept her feet firmly on the ground!"
Singer Grimes, The Hunger Games star Amandla Stenberg and animal activist Kenya Kinski-Jones also join Leon for the campaign.
Aside from her new modeling gig, Leon is studying musical theater at the University of Michigan.
