Lindsay and Ali Lohan are not only attached at the hip — they’re attached at the purse strings. We hear sisterly love isn’t the only gift 15-year-old Ali has been doling out in the wake of her beloved big sis’ split from former lover Samantha Ronson.

In the June 1 issue of Star Magazine, informants reveal that the former Freaky Friday actress is near broke and has resorted to using her kid sister as an ATM in order to make ends meet. Word is Ali’s been footing the bill for Lindsay all over Hollywood since the two began staying together more than a month ago.

“Lindsay has wasted most of her money,” says a Star snitch. “She makes Ali help her out.”

According to the tabloid, Ali — star of the E! reality series Living Lohan — forked over fistfuls of cash on Lindsay’s Malibu shopping spree on May 9. She also purchased lunch for the girls on the way home.
