Donna Mills, 85, Claps Back at Makeup Critics!

Donna Mills showed a side of herself rarely glimpsed by fans when she took critics of her looks to task on Sunday.

The Knots Landing star, 85, revealed just how much effort she puts into her appearance in an Instagram transformation video.

The clip was a response to a user who wrote on an earlier post, 'You wear too much makeup for your age ♡.'

In her video, Mills started out as her , before she snapped her fingers and revealed her makeup-free visage and graying hair.

It was a night-and-day change, with the actress instantly looking years — if not decades — older in her natural state.

'Oh, this comment,' Mills said as she pointed up at the comment on screen.

She was dressed like Olivia Newton-John at the end of Grease, with a black leather biker jacket, a black blouse with a lacy neckline and blue jeans.

Mills also sported what appeared to be a wavy blond shoulder-length wig, and she wore her standard makeup look, which gave her eyes a particularly striking quality.

She let out a playful laugh and added, 'I guess I didn't get the memo,' before snapping her fingers and instantly transforming into her makeup-free self.
