They got engaged via Twitter, and have now used social media to announce their breakup. Yesterday afternoon, Kat Von D sent out tweets that basically spelled out the end of her engagement (and relationship) to deadmau5, saying that "cheating on your loved one is the most hurtful thing one could do." There was no word back from deadmau5 until earlier today, when he stated the following:

"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."

Maybe Kat wasn't as "over" the news of him cheating as she thought she was, and decided to end things before they got married, but they seemed to be so happy. Better to break things off now than going through that commitment, but damn. We wonder what'll happen to "Satellite" now...

UPDATE Kat is going in on the tweets, alleging that she has texts from other women... and that deadmau5 got someone pregnant? This feels hella TMZ, but damn.
