Lindsay Lohan has split from her rumoured boyfriend, according to a U.S. report.

The Mean Girls star is said to have separated from former football player Matt Nordgren after several months of dating.

A source tells, "Their work schedules and the distance just make dating impossible. He really likes and respects her. He thinks she is back on top, emotionally and physically... He respects her sobriety and wishes her the absolute best. They will remain good friends."

Lohan reportedly struck up the relationship with Nordgren, 30, after completing her stint in rehab this summer (13), but is said to have known him as a friend for many years.
