MAMA June and her ex-husband Mike "Sugar Bear" Thompson became embroiled in an explosive row in which their daughter Lauryn "Pumpkin" threatened to beat her father.

In shocking scenes from the reality show, all three parties need to be restrained by crew members  as they furiously yell insults at one another.

Mike evens rips open his shirt in a moment of pure Hulk-inspired rage as Pumpkin is dragged away yelling: "That's why you're a f*****g piece of sh*t father."

The preview clip sees Mike storm round the corner of the studio while angrily pointing at his screaming daughter.

Mama June reacts, threatening: "You f*****g touch her and I will f*****g kill you!"

Mike and Pumpkin both yell "C'mon" at one another as the latter adds: "I swear to God, I will beat your a**"

A member of the crew tells Mike to take a break and he kicks a piece of furniture on his way out.

Meanwhile, a distraught Pumpkin is comforted and June is reassured her daughters are safe.

June has sensationally claimed her ex ’emotionally and physically abused her’ in a shock interview.

The couple split in September 2014, and Here Comes Honey Boo Boo star June has revealed their relationship is now “non-existent”.

Speaking to Life & Style, June reportedly said of her ex: “There was just so much emotional and physical abuse.”

She added: “I just choose not to put my kids through that.”

Sugar Bear, real name Mike Thompson, has since moved on with Jennifer Lamb, and June sent her a word of warning, saying: “Watch out.”
