The daughter of screen favourite Johnny, 52, and singer Vanessa Paradis, 42, has followed her famous parents into showbiz by starting an acting career, following her modelling debut for Chanel in March, reported Daily Mirror.
Lily-Rose, 16, plays the sibling of Natalie Portman in "Planetarium", about sisters who can connect with ghosts.
And she's co-starring with her father in Kevin Smith's latest film, "Yoga Hosers," a horror comedy in which California teens battle an ancient evil.
The film is a spin-off from "Tusk", an earlier Smith film which featured Lily-Rose in a specially written cameo.
