And it appears Lyssa isn't prepared to back down anytime soon after posting a thinly veiled dig at Dog, 66, and his girlfriend online.

The reality star shared hashtag reading "Barking Snakes" to her 314k followers and followed it with an emoji of a dog and a snake.

This isn't the first time Lyssa has taken to social media in rage.

In December, the 32-year-old blasted her father and Moon, who used to be Beth Chapman's assistant, for dating just months after Beth's death.

She wrote on Twitter: "You’re disgusting woman.

"Any person who moves in on a man weeks after losing his wife, who you were supposed to be a ‘friend’ to, Is the lowest scum on the planet-Which for you wasn’t that far of a step down from where you were before.

"God will get you, Mary!"

She also shared a string of now-deleted tweets, which addressed her father directly.

In the online posts, Lyssa accused the TV personality of "blackmailing" her because he wanted to reveal details of her apparent suicide attempts in the past.

She wrote: "Speaking to my dad last night he threatened to tell the world about my suicide attempts, So I feel I have to tell the truth myself, before him as his GF can come out against me.

"Everything I’ve done I admit to. I’m not perfect. I have a history, I have CPTSD, I have relationship problems.

"I’ve messed up and will continue to. But I’ll never be blackmailed. I’d admit to everything. Because I to learn from my mistakes."
