The former X Factor contestant was recently confirmed as the support for the UK leg of Minaj's upcoming 'Pink Friday: Reloaded Tour' alongside Tyga.
"I am so excited," Misha B told Birmingham's Radio Sandwell.
"When I did my judge's houses X Factor performance last year I sang 'Fly' by Nicki Minaj and Rihanna.
"So to be able to say I was singing her songs last year, but now I am going to be her support act on this tour along with Tyga is like really mind-blowing."
She added: "I am probably going to be speechless. Although I'm scared at the same time, I am really looking forward to it."
Regarding rumours of a collaboration on Minaj's new single 'Automatic', Misha B said: "Is that what the word on the road is?
"I can't confirm anything, it's the first I am hearing about that... I don't know anything about that."
She continued: "I really do admire her drive, her passion and courage.
"She is such a great inspiration to anybody on their way up or anybody with a dream. In terms of charisma and stage presence, and just owning what you do she's surpass that."
