Is it prince that plays in Ashanti only you?

No it is not, because towards the end of the video you can get a clear facial view of the guitarist.

Now, from the old rumour hill I have heard that Prince was asked to be in the video. Prince being what he is, naturally refuses. (if he refuses Michael Jackson, why would he accept Ashanti) But yes, it is NOT prince that plays in the Ashanti video.

No prince is not the lead guitarist in the video.His name is 7 Aurelius.An Amazing Producer and Talent.
