Barbra Streisand is expressing regret after letting slip a comment that is seen as an insult to the Fox musical show “Glee.”

The singer was asked Friday whether she would ever consider a role on "Glee," and responded, "Not if I can help it," according to The Hollywood Reporter. But now Streisand is rethinking her comment, writing on her Web site that her response was wrong.

"When asked if I would ever appear on ‘Glee,’ I should have said, ‘You never know.’ It was wrong to say, ‘Not if I can help it,’ " she wrote, according to the piece.

She added that she had been "overwhelmed" preparing for her performance on MusiCares, the Grammys, recording a new album and starting a new movie. "So I couldn’t take on any more work, and besides that, I wasn’t asked. I’m so honored that a lead character on ‘Glee’ is so admiring of my work.," she wrote.
