Mama June and Sugar Bear Thompson are done -- separated -- because she's convinced he's been cheating on her ... sources tell TMZ.
We're told Mama June has repeatedly caught Sugar Bear trolling on online dating sites. One of them is plentyoffish.com, in which Sugar Bear -- with the handle Georgiafighter31054 -- says "i love to hunt fish and ride 4wheelers and have a good time. i luve muddy Boggs and love to ride in the mudd."
AW NO. I really love this family. They're great and show a lot of important family values that a lot of people forget about. Yeah, they might be dirty and do a lot of questionable family activities but they all seem to love each other so much.
