Kat Von D And Nikki Sixx’s Girlfriend Courtney Bingham: Catfight!

Kat Von D might have found a new man in DJ Deadmau5, but does she still carry a torch for her ex-boyfriend Nikki Sixx?

According to Hollyscoop, Kat and Nikki’s current girlfriend Courtney Bingham, a model that he met shortly after he and Kat broke up in late 2010, had a nasty run-in this weekend while attending the iHeartRadio Music Festival in Las Vegas.

Apparently Courtney went to see Kat’s new boyfriend Deadmau5 perform at the concert’s XS after party.

Says one insider, “Kat threw a fit and blocked Courtney from the VIP.”

Courtney was then overheard saying to some people, “The nicest thing I can say about Kat is that all of her tattoos are spelled correctly!”

The reason for Kat’s animosity? Supposedly when Kat and Nikki broke up, she wasn’t ready to let go and tried to get him back, even after he began dating Courtney. Rumor has it that Kat wanted to marry Nikki and is ticked things didn’t go her way.

Kat’s probably not too happy that the tat Nikki got in honor of her (a “K”) has since been covered up with a tattoo of Courtney’s name.

Courtney took to her Twitter Tuesday to post links to the Hollyscoop story (although I don’t see them anymore?), and tweeted, “Haha why do crazy things always happen in Vegas? LOL”

One of her followers then asked her how Nikki felt about it and if he was annoyed and Courtney replied, “Personally I think it’s hilarious!”

Gotta love the drama!
