MTV's "Teen Mom OG" star Farrah Abraham has been argumentative with most of her U.K. "Celebrity Big Brother" housemates since day one.

Abraham showed her craziest behavior yet when she and Atomic Kitten's Natasha Hamilton, 33, fought on Monday night's episode.

House president Fatman Scoop informed the housemates they'd have to ration this week's food supply because inventory was running low.

Hamilton and former porn star, Jenna Jameson, argued about how the food was being distributed. Scoop stepped in and raised his voice to Hamilton, which did not sit well with the pop star who said her own father doesn't speak to her that way.

Her remark upset Abraham because Hamilton had complained in the past about housemates talking about their families.

"Do you know what, when you get upset about bringing up our families, you bring up your dad on the way out?" Abraham said.

"Watch how you talk to people because it's very negative," Hamilton shot back.

The argument escalated with Abraham insulting Hamilton and telling her not to talk about her family in the house. She gestured to the singer with her middle finger.

"You want me to talk some sh*t? Then you better start saying, 'I'm sorry for talking about my dad,'" Abraham shouted.

Hamilton told her to "F**k off," at which time "Big Brother" producers called Abraham into the Diary Room.

"Loose Women" panelist Sherrie Hewson and Scoop attempted to calm Abraham, but she shouted at Hewson not to push her.

Abraham pitched a fit about having to go into the Diary Room. She was furious that she broke her flip-flop on the way.

"I'm not even f*cking wasting my energy to sit back up and down. You can fix my flip-flop which I broke up coming in here," the reality TV star said to producers.

When "Big Brother" producers explained why they called her in, Abraham responded, "What, because I was going to f*cking obliterate the scum of this house? I am straight up going to kill everyone in this house."

Abraham has been nominated by eight different housemates for the first "CBB" eviction.
