Joshua Jackson has blasted critics of Bobby co-star Lindsay Lohan, insisting reports of her party lifestyle do not match her "professionalism" on set. The actor is outraged at the way Lohan has been treated in the press and the criticism she's endured from some of her movie colleagues.

He's adamant the 20-year-old is no wilder than other girls her age, and admires how she keeps her social life and career so separate, despite what others have claimed.

Jackson says, "She's a sweetheart. She's in the eye of the storm all the time. Maybe we expect too much from her privately. We want her to be sexy and then demure on demand. She's just doing what every 20-year-old is doing. But she's very professional on set."
