Jermaine Dupri went live on hisÂ USTREAM account while in the studio with the legendary Mariah Carey. Who in a million years would have thought that “Mariah Carey” would be live on USTREAM? This is a very candid side of the songstress that we rarely get to see and I loved every minute of it! She kept trying to end the show, but yet coming back and forth to speak and be seen. Hilarious.
