Hollywood beauty Mischa Barton regrets her humbles beginnings on U.S. soap opera All My Children.

The former The O.C. actress appeared in two different roles on the long-running TV show in the mid-1990s.

When asked about her worst acting role, she says, "I made a few mistakes in films when I was younger."

"I was also on All My Children for a couple of episodes."

A source told the New York Post newspaper: "Brenda was in the hospital. She had a hysterectomy and Nicole hasn't visited her since. The two have not been getting along lately."

According to reports, Nicole's rift with Brenda could be the cause of 'The Simple Life' star's recent personal problems.

The 25-year-old has reportedly been seeing a therapist to try and combat her low weight.

TMZ has learned that actress Mischa Barton was rushed to the hospital yesterday evening after suffering an adverse reaction to medication.

Sources tell TMZ that the former "OC" star was at a friend's Memorial Day BBQ enjoying a few holiday cocktails when she began to feel extremely ill. Mischa, who has been quite sick with bronchitis since traveling to Cannes, London and Paris the past several weeks, apparently didn't get the memo -- you can't drink alcohol while taking antibiotics!

The 21-year-old celeb was rushed to an undisclosed medical facility in Los Angeles, where we are told she is "resting comfortably."

A rep for Barton tells TMZ that the starlet is with family and "feeling much better."
