Nicki Minaj Joins Instagram to Oust Posers [PHOTOS]: 'Onikam NOT me, It's Barbie B#tch!' Songstress Debuts @allpinkbarbiedreamhouse with Funky Caricatures, Cleavage Shot

Nicki Minaj is sick of posers trying to "steal" her identity on Instagram (@onikam, specifically)... so the former "American Idol" starlet finally made her first official account and deemed it @allpinkbarbiedreamhouse. How fitting!

Not sure why fans associate Micah White's Instagram with the "Super Bass" rapper, but when people search "Nicki Minaj Instagram" on Google, that's the first account that pops up. And also this shady profile. So Minaj finally cleared things up on Twitter on July 5:

@NICKIMINAJ: "I do NOT have Instagram. OnikaM is NOT me. Guess I have to make a real one to counter attack. I'm sure that's why Instagram won't delete it."

Introducing... @allpinkbarbiedreamhouse.

And Minaj is already having some fun with the popular social media/photo-sharing site:

allpinkbarbiedreamhouse: "It's Barbie B#tch!!!!!!!!!!!!!!"

allpinkbarbiedreamhouse: "U was sleepin on me thnkn it was slumber time."

allpinkbarbiedreamhouse: "#GetInTheMyx #PrettyGangOnly who want a Minaj?"

She already has over 82,000 followers. Welcome to Instagram, Nicki!
