Nikki Sixx lashes out at Kim K for promoting make-up line during Okla. tornado

Nikki Sixx has slammed Kim Kardashian on Twitter for promoting her new make-up collection on Monday in the aftermath of the disastrous tornado that destroyed a suburb near Oklahoma City.

After the 'Motley Crue' bassist tweeted about the Red Cross relief for the ruined town, the reality TV star soon followed with her plug on her own makeup line on the website, the New York Post reported.

"Love that I can gradually build the perfect bronzed glow I want with #Kardashian Sun Kissed Tan Extenders," she wrote.

The annoyed rocker then posted an image of Kardashian's post and wrote, "Pick your priority or pick your poison. Pretty embarrassing screen shot Kim," adding, "Isn't your 15 minutes up..."

The mum-to-be eventually posted a sincere tweet for the ravaged state on her Instagram and followed that with a close-up of her "pregnancy lips" with the hashtag, "#IGuessNotABadProblemToHave", a couple of hours later.
