SCANDAL: Mariah Yeater: “Justin Bieber Is The Father Of My Baby!”

Genius. Jimmy is HIGHlarious! Jimmy’s Justin starts the song with: “You said we did it and I’m a dad. My lawyer’s tripping cuz this looks bad. You only said this to get my cash and now Selena Gomez is gonna kick my a$$.”

The chorus goes like, “It’s not my baby, baby, baby. No. It’s not my baby, baby, baby. No. It’s not my baby, baby, baby. No. I’m telling you it’s not mine.”

Personally, I prefer this line: “You said I didn’t use protection. I only lasted for 30 seconds, but that’s not true. No. That’s a lie. It was totally more like 45.” Poor Justin.

Jimmy and his team had less than 24 hours (probably approximately 12 hours) to go come with that hit song, which also included a rap segment. Incredible. Of course, Justin’s a great source of inspiration.
