Kat Von D's life went up in smoke over the weekend.

The tattoo artist, 28, is currently mourning the loss of her hairless cat Valentine, whom she lost in a house fire Sunday. "R.I.P. my little Valentine," she tweeted.

A rep for the L.A. Fire department confirms to that fire fighters arrived on the scene at 11:23 p.m. Sunday night.

"Fire fighters encountered heavy fire with extreme smoke but they were able to get a knock down on the fire," Captain Ruda tells Us. "There was no one home."

"My house burned down last night with my cat inside," Von D, who has been dating Jesse James since August, explained early Monday morning. "Finally get to sleep away the remainder of today. Hope tomorrow is gentler."

Von D (real name: Katherine von Drachenberg) then tweeted a photo of herself surrounding by the charred remains of her home.

"In order to gain everything, you must lose everything," the L.A. Ink star wrote.

According to Ruda, the cause of the fire is still under investigation.
