Nicki Minaj was left stunned when her offer to go and speak to students at her former school was declined by the principal.
The rapper wanted to give a talk to teenagers at LaGuardia High School in New York City to inspire them to pursue their goals and work hard.
Nicki - whose highly sexual video for Anaconda has been criticised in some sections of the media - wanted to do it because of the positive experience she had herself at the educational facility, but she was told she wasn't welcome.
Revealing the snub in a series of Twitter posts, she wrote: "That school changed my life and I wanted to pay it forward to the students there now. I was really looking forward to it ... I guess I'm not good enough ... I wanted to go back to my HS and speak to the students but the new principal declined. No need for me to inspire them, I guess. Smh (sic)"
Her follower @JorianTM tweeted her the message: "@NICKIMINAJ wooow that's so unfair. Did he give any reason why? (sic)". To which Nicki, 31, replied: "It's a WOMAN. And not really (sic)".
Many of the pop star's fans posted messages of support following her revelation.
User @RayYoWTF posted: "Does she not know how much Nicki impacts this generation?"
While @ACminaj95 credited Nicki with motivating him to go to university, tweeting: "Because of Nicki's drive, I applied to two universities. Like I never thought I'd be at that point in my life. (sic)"
Following her posts, the New York City Department of Education has made the decision to investigate Nicki's claim.
