Von D was the first to announce the breakup Saturday with a series of tweets.
"Man ... Can't say I didn't give it my best," she wrote, followed by, "Man, I sure was wrong. But at least he made it a no-brainer to break that off. #lessonlearned."
"Now, we can get all of the 'I told you so's' outta the way ... And move on," she added later. To avoid any confusion, she finally wrote, "Clarification: Deadmau5 and I are no longer together."
Zimmerman also took to Twitter with a series of posts about the split.
"Going to spend a little while screwing my head back on. i guess im not cut out for relationships right now. and that's all i really want to dwell on it right now. ill figure it out. no hard feelings," he wrote.
"it happened too fast, i lost my balance and fell into a familiar dark place that im having difficulty with. she deserves someone stronger."
Zimmerman concluded with, "...and thats it for the personal stuff ... on with our regularly scheduled deadmau5 crap."
