FREAKY FRIDAY star Jamie Lee Curtis has slammed actresses who resort to cosmetic surgery in a bid to regain their youthful good looks - despite going under the knife herself.

The 46-year-old actress has famously enhanced her breasts, undergone liposuction treatment and bought Botox injections - but she now insists it was a mistake she will never repeat.

And she urges other aging stars to shun the escalating trend if they want to look like human beings.

She says, "It is an epidemic which is out of control. The way they are injecting things and freezing things. People are looking like aliens.

"It didn't work when I tried it because it didn't work emotionally - it felt fraudulent. It felt like the act of doing it made me feel ashamed of myself that I would even try.

"I tried lipo and that comes back in other places. And I tried the Botox and that doesn't work because you have no expression. All the actresses now have foreheads like Madame Tussard's wax museum.

"I would never try it ever, ever again."
