Who Did Kat Von D Spend The Holiday Weekend With? (Hint: NOT Deadmau5!)

Kat Von D may be off and on with famed DJ, Deadmau5, but the celeb tattoo artist spent the weekend with another famous face who ended up bragging about it online! So who was Kat spending the holiday weekend with? None other than Demi Lovato! The tattooed X Factor judge took to Twitter to post about her new ink (adding to her growing collection!), courtesy of Kat!

Demi posted a photo of the two ladies and tweeted: "Thank you so much @katvond for my new ink!! I think it's beautiful and I love it!!" 

After responses from fans, she posted another photo of her new arm ink, saying: "Here ya go #ink. And another picture of my new birdies."

What do you think of Demi's new ink - did Kat do a good job on her?
