It was just last month that Kat Von D and Deadmau5 broke up after she caught him cheating on her. Of course Kat has a lot of experience getting cheated on so was able to move past it and now has not only got back together with the DJ, but apparently is engaged after Deadmau5 proposed to Kat on Twitter. Oh yeah, he did. No dinner out or putting out much effort at all. The DJ simply posed a photo of a ring and asked her to marry him. He did not even post the actual ring. He said the actual ring was being changed so the photo he used was a stand in while he put a black diamond in because that is so edgy. You know, because they are both so edgy with their corporate sponsorships and reality shows.
