We all know Nicki Minaj is a colorful character onstage, but she recently had the opportunity to get even more animated for her voice-over gig in the cartoon flick 'Ice Age: Continental Drift,' which is the fourth installment of the popular children's movie.

While the rap diva wouldn't divulge what kind of character she will play in the movie, she did reveal how the role came about to MTV. "My agency sent me out on an audition for some people who wanted to hear me," remembers Minaj. "They knew I liked animation, they knew I liked to do voices, and so they said they were doing that so I thought, 'This is amazing.'"

"The original role that I was up for I didn't get, so I said, 'Oh, OK, whatever.' I was really mad, and the next thing you know, they called me and they said, 'We wrote in a part just for you 'cause we really want you to be a part of this movie.'"

Minaj recorded two voices and left it up to the film's producers to decide which they wanted for the movie. "And I just was screaming and so excited, and I went in and I had a blast," she said. "We'll see what happens."

As we previously reported, 'Ice Age: Continental Drift' will feature the voices of fellow Young Money artist Drake, as well as comedians Wanda Sykes and Aziz Ansari; Jennifer Lopez and Queen Latifah and 'Glee' star Heather Morris. The film will be in 3D and is expected to arrive in theaters on July 13, 2012.
