Emmy Award-winning singer/actress Kristin Chenoweth has defended her use of Botox – insisting she needs age-defying injections to ward off migraine headaches.

Chenoweth, 41, regularly has injections to her forehead, but insists she’s following the Hollywood trend for healthy reasons rather than to look decades younger.

“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),” the former Pushing Diasies star explains.

She insists Botox helps her avoid the crippling headaches that have wrecked havoc on her career.

“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.”
