What happens in rehab should stay in rehab, well at least in Lindsay Lohan’s case.

The Mean Girls actress has dumped boyfriend, Riley Giles, reports People.com.

Sources confirm to the website that LiLo – who met the 25-year-old snowboarder at the Cirque Lodge in Utah where they were both seeking treatment for alcohol abuse – broke up with Giles after Thanksgiving.

"They're over — they've broken up," the source said. "They split after Thanksgiving weekend."

Another source added: "She is concentrating on her life and her career."

Wise choice LiLo.
