Shocking no one, US Weekly now has an unnamed source who claims that Lindsay Lohan takes Adderall “all the time”, and that the drug makes her jittery and increase her weight loss. Lindsay allegedly started taking the drug as a treatment for attention deficit/hyperactivity disorder. I’ve never heard that Lindsay has AD/HD, but that diagnosis makes a lot of sense, especially reflecting back on when she went off the rails. AD/HD isn’t a cure-all explanation for her activities, but it does explain why should be more susceptible to certain bad habits. If my research is correct, Adderall isn’t the kind of drug you’re supposed to take “all the time” – there is a recommended, doctor-approved dosage level, and at this point, Lindsay seems to be taking it for the side effects.

This report comes as Lindsay is starting to defend herself from a new wave of criticism that she’s much too thin. She told E! Online that she’s eating enough, but is Lindsay even a trustworthy source about herself at this point?

After debuting a startlingly skinny figure in Hawaii last week, Lindsay Lohan defends herself against critics who feel she’s recently gotten too thin.

“I’ve been eating enough,” Lohan tells E! Online.

The star — who went through a very public breakup with DJ Samantha Ronson, 31, in April — also says that she used her time in Hawaii to relax with her family and get healthy after what was “a hard month.”

“We’re a tight family,” she says. “We’ve been through a lot so we take care of each other… We went hiking and everything in Maui, so it was really good.”

Still, a source told Us Weekly that the 5’5″ actress showcased a skin-and-bones physique while on the island, adding that “I’ve never seen hipbones that stick out so much.”

In fact, Us Weekly confirms in the current issue that Lohan takes Adderall, a prescription drug usually given to people for attention deficit hyperactivity disorder, to lose weight.

“She takes Adderall all the time,” one source told Us. “She gets jittery because of the way the pills affect her. It’s a major reason why she’s losing weight.”

Instead of focusing on her frame, however, the actress reveals that she is close to signing on the a new film. Although she says she wants to keep the details of the movie deal confidential, she acknowledges that “it has a really good cast.”

Besides movies, she’s trying to relaunch her music career.

“Pharell, please call me back,” she shouts out to the music producer, who she’s hoping will agree to go back in the recording studio with her.

Any words for her ex, Ronson?

“We’re friends,” Lohan says, adding that the two are still “in touch.”

So she thinks she’s about to sign on to a new movie, and she’s begging music producers to call her to re-launch her music career. Sounds… delusional. The only movie she might be signing on for soon would be something pornographic. That’s not a punch line, either, I really think that’s the path Lindsay’s heading for.
