Looks like Kat Von D's on-again, off-again romance with deejay Deadmau5 is off again. On Wednesday, June 26, the L.A. Ink tattoo artist posted a couple of telling tweets suggesting that she had ended her engagement to her fiance because of infidelity.

"Cheating on your loved one is the most hurtful thing one could do. I hate to have to admit that this relationship is indeed over," she wrote. "Onwards and upwards."

A short time later, a fan tweeted, "Don't take him back no matter what. Ur worth more than that." To which Kat replied simply, "Never."

The Go Big or Go Home author, 31, first started dating Deadmau5 (real name: Joel Zimmerman) in September 2012. They broke up briefly in November but reunited shortly thereafter, and he proposed in December via Twitter. "I can't wait for Christmas so...Katherine Von Drachenberg, will you marry me?" the deejay tweeted, alongside a photo of what her engagement ring would look like.

Since then, the couple had been making plans for an underwater-themed wedding inspired by one of their favorite authors, H.P. Lovecraft. In an interview for The Wendy Williams Show in April, Kat gushed that her groom-to-be was "amazing," not just as a boyfriend but as an artist.

"We've been creating music together," she told Williams. "So I think I've met my match."
