A Rep For Mischa Barton has dismissed reports the actress behaved "unprofessionally" while filming a new episode of Law & Order: Special Victims Unit.
The actress, who is playing a prostitute in a guest role on the TV series, allegedly upset cast and crew after repeatedly forgetting her lines while shooting earlier this week (18Jan10).
The former O.C. star is said to have frustrated her co-star Mariska Hargitay by relying on her for cues to finish their scene.
A source tells the New York Daily News, "People close to her were hoping this would get her back on track. But it looks like she's going to need yet another chance."
But a spokesperson for Barton insists there have been no problems: "Everything's going swimmingly on set."
Barton's last TV venture, U.S. fashion drama The Beautiful Life, was cancelled after just two episodes.
