Actress/singer Kristin Chenoweth has defended her use of Botox, insisting she needs age-defying injections to stave off migraine headaches.

The 41-year-old star, who recently hosted the Critics Choice Movie Awards in Los Angeles, regularly has injections to her forehead, but insists she's not following the Hollywood trend to look decades younger.

She insists Botox helps her avoid debilitating head pains, which have threatened to wreck her career.

Chenoweth explains, "The thing is I suffer from migraines. Flashing lights. It's not good for me, so I get three (Botox) shots right there (on my forehead). I was very nervous about it because I'm an actor and I have to move my face. But, without it, I would not be able to sing or perform."
