Honey Boo Boo is mysteriously bailing on public appearances ... and we know the reason -- a smashed Pumpkin.
Boo Boo was a no-show this morning on "GMA" and we're told she won't show up at Katie Couric's show either.
Turns out the kid's family ties are more important than mugging for a camera. She's been spending time in the hospital with big sis Pumpkin, who was badly hurt in the family car accident last week. Pumpkin suffered severe chest bruises, a concussion and weakness in her legs.
She can be annoying, but she's a good sister.
The new season of HBB and brood starts Thursday on TLC.
