VIDEO : Kaia Gerber Just Got Her Fourth Tattoo

Model Kaia Gerber just got her fourth tattoo, and it?s her biggest yet.
According to Refinery 29, on Wednesday, Gerber posted a photo to her Instagram in which she?s lounging poolside in a bucket hat and bikini, revealing some fresh ink on her ribcage.
It is unclear just what the tattoo is of. What is known is that 17-year-old Gerber would likely need the approval of one of her celebrity parents, Cindy Crawford and Rande Gerber, to get tattooed as most laws prohibit anyone under the age of 18 from getting inked.
