Lindsay Lohan says Ali is okay to play

Some folks may be concerned that former actress and model, Lindsay Lohan is so often seen out at clubs with sister Ali, who’s only 15 — but Lindsay assured some reporters it’s really okay.

“She’s tougher than I am,” Lindsay told writers for E. “She has a good head on her shoulders. It was different for me; It all happened really fast and I didn’t have a big sister.” she mused.

Sadly, the roles as LL’s party behavior consultant, medications adviser and skin care doyenne were also unfilled.

And despite her sister’s late nights and long parties, Ali, we’re told, is still focused on school work, “She’s really good about that,” says big Sis. “If I’m going out late, she’ll go home early.”

Of, course, big momma, Dina regards Ali as too important and special to attend a real school, so Lohan junior is now tutored at home.

So what do you all suppose Ali’s courses might be? ‘Snowballing 101″?…or how about, “The Concise History of Rehab” ?

One thing’s for sure — the graduation party [if she even makes it that far] should be a real peach!…
