After a great performance on the series Weeds, ABC confirmed that Mary-Kate, one half of the super Olsen twins, will guest-star in this season of the drama series Samantha Who?.

Samantha Who? insiders confirmed that the 22-year old former child actress and business mogul will play a self-destructive bad girl whom Samantha, played by Christina Applegate, will try to save.  She will supposedly remind the new Samantha of her pre-amnesia life and wants to prevent MK from taking the same destructive path she did.

Apparently, MK is doing quite well.  A source said she had been “terrific” from day 1.  Meanwhile, Executive Producer Don Todd praised her work ethics.

"She showed up alone, ready to work, is great on set and is serious about the job," says Todd.  "This is a girl who's been in front of the camera almost literally her entire life.  She's smart, and she knows what she's doing."

Mary-Kate Olsen began her career in 1987 when she was nine months for the role of Michelle Tanner on the television series Full House.  The twins alternated in the role during the taping of the show, to comply with labor laws.  Growing up, they became a household name especially in the pre-teen market.  Their names have become associated with clothes, books, fragrances, magazines, movies and posters.  Meanwhile, she announced undergoing treatment for anorexia, an eating disorder that resulted in her massive weight loss.
