Kat Von D Breaks Up with Deadmau5... on Twitter

UPDATE: Deadmau5 has responded to Kat Von D's cheating allegations on his Facebook page. Posted the musician: "Kat and I split in November and I moved back home to Toronto. During this time, while we were broken up, I did have relations with another woman. Following that, Kat and I reconciled and I acknowledged being intimate with another person while we were estranged.

"We did move past those issues, and I proposed to Kat in mid-December. At the end of June, it was clear that the relationship was not working and we mutually ended the engagement. I was not, at any point, unfaithful to Kat during our time together.

"I don't wish to go tit for tat with these kinds of pronouncements and don't expect to comment further, but I do believe that those who have expressed concern deserve a more complete understanding of what transpired."

And this is hardly the first time Von D took to social media to accuse a significant other of wrongdoing. The reality star, who was previously engaged to Jesse James, accused her ex of cheating in late 2011:

At least she has 1.4 million people to vent to?
