Lindsay Lohan is a homewrecker!

Lindsay Lohan is a homewrecker, her present toyboy that she apparently met in rehab was engaged to someone else but dumped her for Lohan in a heart beat! Couldn’t Lohan be attracted to guys that have no string? Bad girl, bad girl!

(( Lindsay Lohan recently gushed, “I am seeing someone. His name is Riley. I am really happy.”

However, Us magazine has learned that her new beau, Riley Giles — a snowboarder she met during her two-month stay at the Cirque Lodge treatment center in Utah — has a messy past.

Until recently, he was engaged to Murray, Utah, resident Bree Tierney. “Riley just stopped calling Bree and never told her about Lindsay,” Bree’s mom, Tess, tells Us. “She found out by seeing photos. It destroyed her.”
