Bette Midler's selfie challenge for Kim Kardashian

Singer Bette Midler has challenged reality TV star Kim Kardashian to put her selfies to work "for a good cause".

On Wednesday, after slamming the "Keeping Up With the Kardashians" star for posting naked photographs online, Midler asked Kim to donate to her charity, Stages for Success, which aims to improve auditoriums in public schools for child singers and performers, reports aceshowbiz.com.

Midler uploaded a photoshopped image of herself holding a cardboard sign which read, "Like Kim... Put your selfie to work for a good cause!"

In the image, she was seen wearing a black brassiere and matching panties.

"Kim Kardashian, put your selfie to work... for a good cause! Donate, I'll match $2-1," Midler tweeted, adding a link to her charity page.

Before asking for donation, Midler addressed Kim's tweet which asked her to send nude photographs.

"Kim Kardashian wants me to send her my nudes! I'll send them right over, but the lighting's bad right now since she threw all that shade!" she wrote.

Midler has been in a war of words with Kim for several days now. The drama began when she said that Kim had to "swallow a camera," if she "wants us to see a part of her we've never seen."
