Lindsay Lohan New and Improved

?OK! magazine has obtained pictures of Lindsay Lohan in rehab.? How odd she is sitting right outside for them to see what she is doing?

In one perfectly posed shot, a demure Lohan, her hair pulled tightly back, is reading “Alcoholics Anonymous,” AA’s 164-page “Big Book,” which mixes personal stories of redemption with a description of how the program works.

Other photos in the issue that hits stands today portray the rehab regular cleaning up her act after her July 24 bust for alleged DUI, driving with a suspended license and cocaine possession.

“She really is taking it seriously,” OK! Editor-in-Chief Sarah Ivens said. “She’s replacing L.A. and smoking with yoga and reading.”

And, Ivens said, “she hasn’t looked this good in years.”

Lohan spends her days writing in a journal, soaking up “spiritual classes” and working shifts at Smith’s, a nearby supermarket, where her earnings go to a local charity, the magazine said.

If that gets too blue collar for her, a source said Cirque offers “equine therapy, where patients care for horses to help them with issues of trust.”

“She’s been really worried about the influence she’s having on her little sister Ali [13],” Ivens said.

“That’s why this time she’s determined to sort herself out, because she doesn’t want her Ali to grow up and suffer the same things she’s suffered.”
