Kat Von D and Deadmau5
Her romance with DJ Deadmau5 started back in September, but the couple quickly split in November. “Man...Can't say I didn't give it my best." She later posted, “Man, I sure was wrong. But at least he made it a no-brainer to break that off. #lessonlearned.” Deadmau5 proposed via Twitter one month later. Of course, they sealed their love with a tweet.
