Abdul says she told them that Goodspeed had been stalking her for years, but they still brought her in to audition on the show.
People reports that Abdul, in a Sirius XM radio interview on "Barbara Live!" with Barbara Walters on Monday night, said she begged producers not to let Goodspeed audition for Season 5.

"She had been writing disturbing letters for 17 years, almost 18 years," Abdul, 46, told Walters. "We had restraining orders at times."
On the day of Goodspeed’s audition, "Idol" producers told Abdul they had found — and were about to bring in — a fan who was "crazy about" Paula.
Abdul objected. "I said, ‘This girl is a stalker of mine. Please do not let her in.’ Everyone knew. I was shaking."
The producers ignored her, saying that they wanted the "entertainment value."
Abdul also claimed that Goodspeed showed up at auditions in Las Vegas and tried out for Season 6. After an audition, Goodspeed was able to follow Abdul home and get her home address.
From then on, Goodspeed sent naked pictures of herself to Abdul and threatened her with "bodily harm" in some letters.
"She said the only way I will serve her purpose is when I’m up in heaven being her guardian angel."
OMG, scary! So why is Paula still on “American Idol”?
"Well, I’m under contract."
