Lily-Rose and Harley co-star in Smith's upcoming film, 'Yoga Hosers.'
Kevin Smith is a proud papa.
The Clerks director shared a photo of his 16-year-old daughter, Harley Quinn, attending prom with her friend and Yoga Hosers co-star, Johnny Depp's 17-year-old daughter, Lily-Rose.
"Last night, the @yogahosers went to Prom! @harleyquinnnn_ & @lilyrose_depp had dates of course but (ever on guard for thee) they were there strictly to chew bubble gum and squish Bratzis! And from all reports, they were all out of bubble gum," the 45-year-old filmmaker captioned the pic.
