"Hope they haven't yet sent out save-the-date cards!

Six months after announcing their engagement, Kat von D and Jesse James have called it quits.

Breaking the news on her Twitter page late Monday, L.A. Ink tattoo artist von D, 29, offered a short statement out of respect for her former fiance.

"I am no longer w Jesse, and out of respect for him, his family and myself, thats all the info I'd like to share. Thanks for respecting that," von D (real name: Katherine von Drachenberg) blogged.

Engaged since January, von D and James, 41, first stepped out as a couple in August 2010: making out at a Las Vegas museum exhibit and then holding hands in Fredericksburg, Texas.

In a promo that began airing earlier this month for her TLC series, L.A. Ink, von D gushed about her then-fiance. "I feel like I'm the luckiest girl," she said in the clip. "I don't care what anybody thinks."

This would have been the second marriage for von D and the fourth marriage for James, whose exes include Karla James, porn actress Janine Lindemulder and, most famously, Sandra Bullock.

James' six-year marriage to Bullock famously ended with the revelation of his affair with numerous women -- including Michelle "Bombshell" McGee, a stripper with a similar plethora of tattoos."
