Jessica Simpson mom-shamed!

Sometimes you have to feel bad for celebrities.  They can't post ANYTHING on social media without being criticized for it.  That's gotta get old.

The other day, JESSICA SIMPSON posted a video of her husband ERIC JOHNSON in a pool, flipping their 4-year-old son Ace way up into the air and letting him land in the water.

The thing is, the kid had a CAST on his arm.  Jessica captioned the video, quote, "A broken bone doesn't hold this kiddo down #WaterproofCast"

And of course, her followers started complaining that Eric was being too rough with the kid.
