In a police report exclusively obtained by The Sun, Malorie’s grandmother Janice Bollen, who has appeared on the MTV series, claimed she arrived home intoxicated at 11:13pm on Saturday, February 1.

Janice, 65, claimed Malorie, 20, went into the bathroom and “fell” into the door, waking up her daughter Emerson, 1, and “causing her to cry.”

The report continued to claim: “Ms. Bollen advised she picked up the infant child to comfort her and Ms. Beaver insisted on taking her to the bedroom.

“Ms. Bollen reluctantly gave Ms. Beaver her child, as she was concerned about her falling.”

The report obtained from Madisonville Police Department in Tennessee continued: “She advised Ms. Beaver began being loud and it scared the child so she wanted to sit in her lap, which hurt Ms. Beaver's feelings.

“She advised Ms. Beaver began saying bad things about her and then grabbed her arm in an aggressive manner twice.”

Janice explained how she threatened to call the police if she grabbed her arm again.

But Malorie “told her to go ahead and continued to be verbally aggressive toward her.”

According to authorities, Malorie “appeared to be intoxicated due to her being unsteady on her feet and having slurred speech.”

The arrest comes after Malorie moved in with her grandma after publically feuding with her mom, Stephanie, and sister Rachel.

She posted on her Instagram story prior to the arrest: “@Stephbpolo is just mad because I am getting my s**t together. Like damn you’re supposed to be my mama why can’t you be happy for me for once?”

But it looks like the arrest has resolved the Beaver family feud, as Malorie posted with her mom and Rachel on her Instagram Story following the arrest.
