ESPN Host Michelle Beadle -- Rips Kim Kardashian ... She's a Dolt

So ... ESPN host Michelle Beadle took a shot at Kim Kardashian and her big fat ass.

After Kim K posted her brand new naked pic, Beadle went to Twitter to mock the reality star.

"Just purchased $633 in baby oil and performed an at-home lobotomy...let's do this. #BreakTheInternet #MoonRiver."

She later added ... "Are we done talking about giant, greasy poo-makers yet? #CometLanding."

Beadle isn't the only celebrity to go after Kim -- Chelsea Handler implied Kim's ass is fake and Naya Rivera also threw shade ... saying, "You're someone's mother."
