This information came from dontdatehimgirl.com but I'm not sure it's still posted up there. He's aged some since this was posted on DDHG.
“Ladies be on the lookout for this man. His real name is DeHaven Irby and he’s 38 years old. Originally he’s from Brooklyn NY (Marcy Projects). If you meet him he’ll impress you by talking about all the great plans that he has to make a lot of money. His greatest achievement in life was selling drugs with Jay-Z back in the day. Although Jay-Z has disowned him since 1998. Recently he made 3 You Tube videos about a book/dvd that he was supposed to release (male superhead) exposing Jay-Z. He had a web site, and another web site where people could comment or vote on whether he should expose Jay-Z or not. Turns out the only one who was exposed was DeHaven. The site has been up since August 07, and I’ve learned that 1) Dehaven likes to get head from young men while in jail 2) Dehaven has 3 children he claims 3) Has 6 children that he does not claim 4) He’s engaged (but visits me each time he’s in Cambridge 5) Has no money 6) Is hated/despised by pretty much everyone that knows him. I dated him for 2 years before he went back to jail in 03. Shortly after dating him I found out I had Genital Warts (HPV). We had been using condoms only half the time that we were having sex, but I wasn’t sure if I had contracted them before or after we started being intimate. So I let that one slide. Then on my following PAP appointment, it was discovered that I had Herpes. My life was shattered. I knew that I had been feeling itchy down there but I never in a million years would’ve thought that I would have herpes. Then I learned that he was sleeping with a woman my apartment complex and she’s the one who gave him Herpes. I had to move because her and her girl friends wanted to fight me for no reason. Dehaven is always in and out of jail, and when he’s home he never has a job. I once asked him how come he don’t get a parole violation for not worked and doing whatever when he’s out. He just told me that ‘He had connections.’ Turns out his connections are Federal connections. This man has been a Federal informant for the past 10 years. I found that out when I saw a check that he had from the government. So now he’s a snitch. I can’t believe this man could be so foul”
