Wow. This will be extremely dreadful! Ke$ha?? Ewww! Not only does she looks like trailer trash and a bar hooker but she's also just as talentless as Rihanna and she's only hot for the moment. I like Nicki Minaj but only for her lyrics and her delivery (sometimes). Other than that I hate her fabricated image. Nicki hasn't even released an album, so why would someone want to see her perform verses from OTHER artists' songs? Smh. And of course Rihanna isn't such a savvy performer herself. She has a slew of hits to perform but I'm still not convinced she's a good enough entertainer/performer. But I must say it is smart to incorporate Pop (Ke$ha) and Rap/Urban (Nicki) to create more ticket sales because RIhanna is kinda in between Pop and Urban.
