See how you can make a headline to make something look really juicy? Unfortunately this story is anything but juicy. Selena is going to finally have a sibling though. Selena announced that her mother is expecting a baby and it is not with Justin Bieber. Well, you never know. I mean if he could have sex with Mariah Yeater, he presumably would be willing to have sex with anyone. It turns out though Selena's step-father is the baby daddy. Selena's mom had Selena when she was 16 years old. Her mom is now 35 and her husband looks a bit younger.
