Mama June's former brother-in-law Lee Thompson is basically calling her a liar.

Honey Boo Boo's Parents Announce Their Split 

Thompson, known as Uncle Poodle on Here Comes Honey Boo Boo, sat down with Dr. Phil and implied that Mama June and sex offender Mark McDaniel are more involved than she lets on.

"That weekend we were together, they acted like [a couple,]" he said. "They were all lovey-dovey in the back seat, holding hands and kissing each other."

Mama June & Sex Offender Spotted Holding Hands? 

Uncle Poodle previously explained to the National Enquirer that McDaniel accompanied him, his fiancé, June and Alana "Honey Boo Boo" Thompson during a small trip to a casino in Cherokee, N.C. on Sept 12. The five of them shared one hotel room - Uncle Poodle and his fiancé slept on one bed while June and Mark took the other. He also said Mama June let her 9-year-old daughter sleep in a queen-size bed with her and McDaniel.

TLC canceled Here Comes Honey Boo Boo in late October - despite its popularity - after news broke that Mama June was seen with the sex offender. The 53-year-old was convicted in 2004 for molesting Mama June's daughter, Anna Cardwell, when she was eight. June was also dating him at the time of his conviction.

Mama June claims she's only seen McDaniel twice since he left prison and once was by coincidence. Uncle Poodle, however, also said he doesn't believe that.

As for Uncle Poodle's relationship with the family now, he said, "I haven't seen June or talked to any of them since all this came out. She told me if I stepped foot on her property, she'd have me locked up. "
