Looks like Lydia Hearst-Shaw won't be playing Lindsay Lohan after all.

Though screenwriter Charles Casillo recently told New York Post's Page Six that Hearst-Shaw, 26, would play a Lohan-like "bratty movie goddess in and out of rehab," the model-heiress denies that she's attached to star in the comedy Dogs in Pocketbooks.

"Just so we are all clear, my hair is red because I am the new face of Schwarzkopf color," Heart-Shaw tweeted. "I am a model. I dyed my hair to front the campaign."

Lohan, who is currently a patient at the Betty Ford Center, has yet to comment on the rumored role.

"As for any theatrical roles I am currently filming Two Jacks directed by Bernard Rose. My next project is Catwalk by Tony Hickox," Hearst-Shaw added. "Thank you all for your messages of encouragement during my transition into acting. I truly love and appreciate it. At this time I am not officially signed onto any other projects. Thank you."
