A judge has denied bail for a California man charged with stalking former American Idol finalist Jessica Sierra.

Circuit Judge Walter Heinrich said during a hearing Monday that Daniel Robert Young, 59, was a flight risk and possibly a danger to the 20-year-old singer and her family.

Sierra says she's "relieved, for now, just knowing my family is safe and I'm safe."

Young began calling Sierra's grandparents' Tampa home in October pretending to be a record producer and trying to get Sierra's phone number, she testified.

Police said Young left voice mail messages telling Sierra that he loves her and was willing to go to jail for her. He sent her a necklace, a bracelet and dozens of long-stemmed roses after seeing her singing on the Fox talent show, police said.

"I told him, `You are scary. You're scaring me,'" Sierra said in court Monday. "He said, `How do you know I'm scary? You don't even know me.'"

Young was arrested last week after he flew from California to Tampa and called Sierra's cell phone twice asking her to pick him up, authorities said. Sierra then alerted police, who met Young at her grandparents' home.

It was not immediately known if Young had an attorney. His driver's license lists a post office box address in Pearblossom, Calif. Records show he has lived in San Bernardino, Pasadena and Little Rock, Calif.

Sierra was one of the 10 finalists on American Idol last year.
