KAT VON D, DEADMAU5 PART WAYS

The 30-year-old tattoo artist announced their split on Twitter Saturday in a series of tweets. "Man . . . Can't say I didn't give it my best," she wrote. "Man, I sure was wrong. But at least he made it a no-brainer to break that off. Lesson Learned." In mid-September, a source confirmed to Us Weekly that Kat Von D and the Canadian DJ, 31, (real name: Joel Zimmerman) were dating after meeting at a party.
