Kat then added, ''Onwards and upwards'', sharing a photo of a heart inked on her hand along with the words, ''Go out into the world with Love''.
Her fans were quick to offer support, with one posting, ''Don't take him back no matter what. Ur worth more than that'', and another incredulously ranting, ''But you're so perfect. Why would anyone do that to you?!''
Torn engagement
The L.A. Ink star began dating Deadmau5 - real name, Joel Zimmerman - in September 2012. The pair broke up briefly in November amid rumours he had cheated on her, but reunited shortly afterwards, with the Canadian DJ proposing to Kat via Twitter in December.
The couple - who have matching star tattoos under their eyes - were planning an underwater-themed wedding in August inspired by one of their favourite authors, H.P. Lovecraft, which they hoped would be ''the furthest thing from traditional.'' The ink-mad beauty was previously engaged to Sandra Bullock's ex-husband Jesse James, and publicly accused him of cheating on her with over 19 women after their split.
