It looks like Kat Von D has struck out in the love game again.
Starting earlier in the week, with a tweet that simply read, "Oh, my heart," Kat hinted at turmoil in the couple's relationship.
However, on Wednesday, Kat opened up the floodgates, revealing what was really bothering her.
"Man, I'm a fool," she wrote. "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."
The couple, who announced their engagement on Twitter in late 2012, had been on and off for a while prior to putting a ring on it, but it looks like everybody knows where Kat draws the line in terms of betrayal.
Before dating Deadmau5, Kat was engaged to notorious serial cheater Jesse James, who she claimed cheated on her with 19 women during their year-long relationship.
Deadmau5, a prolific tweeter himself, has remained mum on the issue, choosing to keep his tweets focused on his music, although he has notably unfollowed his would-be bride.
