Honey Boo Boo and her family are famous, but they're not rich -- at least not according to Mama June.

Mama tells TMZ that the "lion's share" of earnings from their reality show Here Comes Honey Boo Boo -- $15,000 to - $20,000 per episode -- is being equally divided into trust funds for her five girls. They won't see a cent until they hit 21 -- except in case of medical emergencies or for school. In fact, Mama says she never even gets her hands on the money. "TLC puts the money into the girls' trust accounts for me and then I get an email telling me how much everyone gets." She says they pay their bills from the money her husband Sugarbear makes as a contractor. The family's only major purchase since becoming famous is a 2005 Ford Expedition.
