Lindsay Lohan's wild partying is worrying her grandmother, who insists all the young actress needs is to find love.

TheMean Girlsstar, who recently split from restaurant heir Harry Morton, is often hitting headlines with her socialising, and now Marilyn Lohan has voiced her fears for the 20-year-old.

She says, "If Lindsay would get herself a stable boyfriend, I think everything would be better. It's such a shame she's no longer with Harry. He was good for her and she seemed more settled."

"She needs a relationship to keep her on the right track."
