Already accused adultress Lindsay Lohan is now being fingered in the breakup of current boyfriend, Riley Giles, recent engagement. The twenty-one year-old actress confirmed reports she is dating the California-based X-Games star earlier this month. The pair met at Utah’s Cirque Lodge Treatment Center. We now hear Riley was already engaged to Utah resident Bree Tierney when he began boinking Hohan. Bree’s mom, Tess, says, “Riley just stopped calling Bree and never told her about Lindsay. “She found out by seeing photos. It destroyed her.”
