LOS ANGELES -- Miley Cyrus says she has not been battling the swine flu despite what her former Hannah Montana co-star Cody Linley said on camera.

On Friday, Cyrus spoke with Billy Bush on his radio show and said she never had H1N1. The performer said she just had a bad case of strep throat and was "really, really sick."

"I'm much better now, thank goodness," she said.

In two separate interviews with Reelz Channel this week, Linley said the 16-year-old pop star was suffering from the swine flu virus.

He said he talked to Cyrus on the day she fell ill and ran off stage during her recent concert in Utah.

"She said she felt really bad. She really didn't understand what was happening but she just got really sick and she had to run off stage because things were just, like, on her heart too heavy," he said.

A day later, he said, Cyrus told him the diagnosis.

"Then the next day she told me she had the swine flu," he said.

Linley said in the interveiw that he hadn't talked to Cyrus "in a few days."

Thursday night, he said Cyrus had recovered from the illness.

"She's doing alright now. She's better. She's healthy," he said, adding that she was sick with swine flu about "a week ago."

Linley is perhaps best known for his recurring role as Jake Ryan on Disney's "Hannah Montana." He was also a contestant on the seventh season of "Dancing With the Stars."

Cyrus has a concert scheduled for Sunday at the Nokia Theatre in Los Angeles and is in the midst of her fall tour. The teen pop star ran off stage during a Sept. 29 concert in Salt Lake City, Utah and had to take a 15-minute break in the middle of performing before finishing her show. She also rescheduled a show in Omaha, Nebraska because she was sick.

A Nokia spokesperson told KTLA that Sunday's concert has not been canceled.

Calls to Cyrus' reps have not yet been returned.
