Lindsay Lohan and Riley Giles, the 25-year-old snowboarder she met in rehab, have ended their relationship, sources told People magazine.
"They're over — they've broken up," the source said. "They split after Thanksgiving weekend."
"She is concentrating on her life and her career," another source said.
Lohan, 21, checked out of the exclusive Cirque Lodge in Utah on Oct. 5. She had been there since August.
