Tattoo artist queen Kat Von D made her break up with DJ Deadmau5 more than official yesterday when she attacked him on her Twitter, calling him out on lies he told the public as well as revealing secrets about their relationship.

The quarrel started over a Facebook post that breaking of the engagement with Kat Von D had been a mutual decision. He also stated that he had never cheated on Kat, rather when they broke up mid-November he had been seeing someone, but the two worked through that issue after Deadmau5 proposed to Kat in December.

However, Kat believes the post was full of lies. According to Perez Hilton, Kat took her anger out on her ex through her Twitter, tweeting at Deadmau5 and calling him a sh*tty liar and a cheat. She threatened to screenshot the texts and phone calls between him and the multiple women he was with when they were on a break in November. She also asked him about a pregnancy and demanded that he never speak her name again.

The tweets that Perez had posted have been taken down, but Kat didn’t remove the heartbreaking tweet that read,

“Cheating on your loved one is the most hurtful thing one could do. I hate to have to admit, that this relationship is indeed over.”
