Mirror, Mirror, on the wall, who has best booty of them all? Nicki Minaj in bondage

WE all know how annoying it is when you get to the doctor's surgery and the only magazines in the waiting room are from 1987.

So it's no wonder celebs get bored on the roador at photoshoots, travelling from venue to venue, arriving to find the minions have messed up the rider and 'NOT STOCKED VOGUE!'
And if there's no reading materials on offer, and you've already scrolled through the last 24 hours of your Twitter feed, what else is there to do?
Not even sipping on cocktails or scoffing back a personal chef-created delight is an option when you've got to twerk it, flip it and reverse it onstage in just a few hours.
Which leads us to… admiring one's own reflection.
And Nicki Minaj is certainly excelling at this weekly activity with fluidity and grace.
Instead of sitting backstage twiddling her thumbs, the Pink Friday chart-topper has been busy whiling away the minutes appreciating hers truly.
Clearly not a selfish individual, the 31-year-old also shares her talents with her online army by uploading countless snaps on Twitter and Instagram.

The latest boob-baring, self-appreciating Kodak moment comes in the guise of a leather-clad snap.
Dressed head to thigh in Moschino, the Big Apple resident models a leather beanie, bondage basque and hotpants combo from the fashion brand.
The all-black ensemble is blinged up with the company's iconic font in chunky gold emblazoned across her headgear and cleavage.
Completing the look with fishnets and a rounded derrière for maximum fan appreciation, Nicki certainly rivals the leading artist of ego mania, a certain Ms Kardashian.
Meanwhile, following a cameo in upcoming movie The Other Woman, Leslie Mann revealed that co-star Nicki couldn't be bothered to remember her name.
During a Twitter takeover for Yahoo Celebrity, Judd Apatow's wife Leslie wrote: "Nicki Minaj never remembered my name. She just referred to me as 'lady'.
"She would just say, 'Come, lady.' And I was like, 'Ok!'"
Defending the Starships songbird's honour, Kate Upton chipped in: "You know why she probably didn’t remember your name? It’s because she was really overwhelmed."
The only thing this lady would be overwhelmed by is her own reflection.
