HONEY BOO BOO... INVITED TO THROW DOWN WITH TNA WRESTLING STAR,,,

Honey Boo Boo is finally getting the chance to learn how to put the moves on fully-grown men -- Lady Detective has learned, the 7-year-old just got an offer to TRAIN with a pro wrestling company ... and one of the trainers is none other than TNA wrestling star Robbie E!!!

In case you didn't know, Alana "HBB" Thompson and her family are huge wrasslin' fans -- in fact, just this month, the Thompsons got into the ring at a local wrestling event in Alabama ... and even took part in the match.

Now James Pittaro, the owner and CEO of D2W Pro Wrestling Academy in New Jersey, tells Lady Detective , he wants to make HBB's wrestling aspirations legit -- by turning her into a fully-trained (fake) killing machine. Pittaro is so serious about the offer -- he's even willing to fly HBB and any member of her family out to his training facility ... and provide hotel accommodations. So far, no word on whether HBB will accept the offer.
