Lindsay Lohan spent two months in a rehabilitation clinic last year
Actress Lindsay Lohan has been given a guest part in US sitcom Ugly Betty, according to the ABC TV network.
The 21-year-old will join the series for six episodes, playing a mean former classmate of the main character Betty.
She will make her debut on the show in this season's finale and will then appear in five episodes next year.
Lohan has not appeared on screen since last year's flop I Know Who Killed Me, and was jailed last year for drink-driving and drug possession.
The actress began her career as a child, appearing in a remake of The Parent Trap.
More recently, she has starred in Freaky Friday, Confessions of a Teenage Drama Queen and Mean Girls before struggling with alcohol and drug problems.
She was jailed last November for 84 minutes after admitting to drinking and driving as well as cocaine possession.
Lohan's appearance on the small screen follows a similar move by troubled singer Britney Spears, who appeared on the sitcom How I Met Your Mother.
