Lindsay Lohan clearly took her latest rehab sentence to heart last night ... Absolut-ly ... she was back on the nightclub circuit.
Lindsay went full camouflage as her SUV pulled up to the AV Club in Hollywood. With a blanket covering her face, she clearly did not want to be seen. Problem was ... there was a gaggle of photogs she couldn't shake, so a frustrated LiLo beat a hasty retreat without ever entering the club.
As you know ... a judge essentially told Lindsay she had a big fat substance abuse problem and ordered her to spend 90 days in lockdown rehab.
