Minaj is helping promote the Casio brand of TRYX cameras.
'I'm not a big electronics person usually, but it's really sleek, it's real sexy,' said the 26-year-old, who has recently been in talks with pop star Britney Spears as a possible replacement for Enrique Iglesias on Spears' Femme Fatale Tour.
'I am in talks of joining Britney Spears, yeah,' Minaj said to MTV in the British accent of her famed alter-ego Martha. 'I'm in talks about a lot of things, ya know. I don't know - oops, I did it again.'
Talking about the camera, the artist, who is on tour with Lil Wayne, added: 'This is the Casio TRYX, and this is my baby. This pink - I don't think this one is in stores yet. I'm going to beg them to put this colour in stores because the Barbs and the Ken Barbs need this one. I'm actually auctioning this one off for the tsunami relief in Japan. I'm really super excited. It's dope to launch a camera, but we can also give back. So hopefully we'll see how well this goes, and it will all go to helping the people out in Japan who are dealing with the disaster.'
