Mike "Sugar Bear" Thompson apparently isn't happy his ex-girlfriend of 10 years, "Mama June" Shannon, is dating a registered sex offender who allegedly molested one of her own daughters in the past.

The Here Comes Honey Boo Boo star is "a little bit" upset Mama June is letting Mark McDaniel, a convicted child molester, around their daughter Alana "Honey Boo Boo" Thompson, according to TMZ.

After Mama June and Sugar Bear split back in September, Mama June got involved with Mark, who was indicted for aggravated child molestation and aggravated sexual battery on Mama June's daughter Anna Cardwell, now 20, in June 2003 for multiple abuse instances in the year prior, RadarOnline reported.

While the Henry County district attorney's office reportedly eventually dismissed its charges against Mark, he was later convicted on aggravated child molestation charges in another case in nearby Spalding County -- a conviction that resulted in him spending the next 10 years in prison.

Mama June has repeatedly publicly denied she's dating Mark despite numerous reports and "compelling evidence" she is, in fact, involved with him. Photos have surfaced in recent weeks of Mama June and Mark together as well as one in which Mark is touching Alana's arm. 

Sugar Bear, who has only seen his daughter twice since TLC announced Friday it's canceling the Here Comes Honey Boo Boo reality series, also addressed rumors Mama June had cheated on him.

"I don't know. I hadn't read that today," Sugar Bear told TMZ. "I'm upset [the show] is canceled."

Mama June has three minor children -- Alana, 9, Lauryn "Pumpkin" Shannon, 14, and Jessica "Chubbs," 17.
