Lauryn Hill's ex-Rohan Marley says Wyclef Jean knew all along he wasn't the father of her baby and is just trying to sell books. In fact, he says he doesn't believe Wyclef was cheating with Lauryn at all.  Check out Rohan coming to Lauryn's defense and calling Wyclef a liar inside........

As Wyclef Jean continues his Purpose book tour where he claims Lauryn Hill led him on about her first child's, Zion's, paternity, Lauryn's baby daddy Rohan Marley says Wyclef "knew from jump that was my son from the day [Lauryn] was pregnant."

Interestingly, Rohan revealed to TMZ that Wyclef was actually the one who hooked up him and his former fellow Fugee member Lauryn.  "They were definitely not messing around, or he would never have given me the okay."  Rohan adds that Wyclef is  "just saying false things to get book headlines."

Wow.

Despite when Rohan has said, Wyclef is sticking to his guns telling TMZ, "There is no way that I would have shown up in the hospital in that circumstance to wait for a baby to be born if it was not mine. The idea of a memoir is to tell the truth. I know that often the truth hurts, but a lie hurts even more."

Hmm....we wonder if Lauryn will ever give HER side of the story...
