Lindsay Lohan’s uncle, Matthew Sullivan, was arrested earlier this month for DUI and marijuana possession. He blew .13 on the Breathalizer, well over the legal .08 limit. Meanwhile, Lohan is dating snowboarder Riley Giles, whom she met in rehab. Giles, 25, spent time in jail for DUI and was arrested after he forged drug prescriptions. He should fit in perfectly with LiLo’s family.
