Looking, well, flawless, the self-proclaimed "Queen of Rap" rocked the mic wearing a multi-colored Versace catsuit to match SLAYoncé's leotard by the same designer, a look that's been a fan favorite.
So far, Nicki has been the only guest artist to grace the stage at Bey and Jay Z's 'On the Run' Tour. The power couple brought the house down on their own every night during the North American leg of OTR.
The husband and wife understandably wanted to switch it up given that this is the first of two shows in the City of Light, both of which are being filmed for a September 20th concert special on HBO. That's right, we'll get to watch the curvalicious divas do their thing from the comfort of our homes soon enough.
Nicki shared the selfie above of herself doing a kissy face next to the singer backstage after the show (peep Jay in the background). "The QUEEN, could never thank you enough," the rapper wrote.
We wonder what other surprises the Carters have up their sleeves for tomorrow, which is the final date of the OTR tour (for now). An appearance by Blue Ivy, maybe? We all know that everyone loves that!
