It was a weekend that will be tattooed in Kat Von D's brain forever. The L.A. Ink star and girlfriend of notorious philanderer Jesse James shared the bad news via Twitter that her house burned down, and her cat, Valentine, died in the fire. She tweeted a picture of herself inside the badly burned remains of the house, writing "My house burned down last night with my cat inside. Finally get to sleep away the remainder of today. Hope tomorrow is gentler." Probably couldn't get any worse unless Michelle "Bombshell" McGee showed up on her charred doorstep. She then tweeted a shot of the deceased hairless kitty and wrote "R.I.P. my little Valentine." Kat Von D, aka Katherine Von Drachenberg, then embarked on a book signing tour of Canada, then Europe, according to her Tweets. She's promoting her second book, The Tattoo Chronicles.
