Lindsay Lohan has faced her fair share of critics throughout her career.
In exclusive photos from the two-hour special, Lohan, 25, guest-starring as herself, channels her inner judge (the showbiz kind) as she sizes up the competition at Nationals, where the glee club is vying for top honors after last season’s upset. They’ll take on show choir nemesis Vocal Adrenaline in front of a panel of celebrity judges, including Lohan, Rex Lee and Perez Hilton.
