In his dishy new memoir, Young, Rich, and Dangerous: The Making of A Music Mogul, Jermaine Dupri looks back on his successful producing career and the big names he worked with – to say nothing of the one singer who stole his heart: Janet Jackson.
At Monday night's Manhattan launch of the book, the 35-year-old hip-hop impresario and rapper, with a very svelte Jackson at his side, told PEOPLE: "I'm excited. I get to add the title 'author' to my titles, I guess. ... I can't wait to get to a bookstore and see it tomorrow."
Besides Jackson – who said of her boyfriend's book, "I think it's awesome" – also at the hotspot Marquee to help celebrate the newly published author: rapper Nas and wife Kelis, Boyz II Men and Joey Fatone, who told PEOPLE, "I haven't read the book, but I am excited to read it."
