Just like Mariah Yeater is treating this whole Justin Bieber baby daddy mess as an excuse to get paid, her ex-boyfriend feels the same way. According to TMZ, Mariah's ex-boyfriend and probable baby daddy Robbie Powell wants to take a DNA test. He thinks he is the father of the baby and thinks Mariah is just doing this to make money. He is saying this as he "examines offers" to tell his own story. Seriously? Why do I want to hear from this guy? Why do I want to hear any more from Mariah either? Just tell me if Justin is the baby daddy and lets move on because there are plenty of other trashy people who want their 15 minutes and you are blocking their space.
