"Beliebers" know of the baby-drama that plagued the life of their famous teenage heartthrob, Justin Bieber, last year. While the Canadian crooner may have kept mum about the issue during it's' reign, Justin has gone all-out against Mariah Yeater in his latest album, "Believe".

The 18-year old teenager blurts it all in a song, "Maria".

The paternity drama was one hell of a bumpy ride for the then 17-year old, Justin Bieber. From courtrooms to DNA tests, Justin Bieber went silently through it all. Not once did Justin speak up on the issue. Instead, Justin lived his life with Selena Gomez as peacefully as possible as if Mariah Yeater did not exist.

Now, Justin Bieber has lain off the silent treatment and is jam-packed with teenage resentment. Earlier this year, Justin took to Twitter to express his irritation and subtle hate towards the woman who claimed she was carrying Bieber's' baby.

"Dear mariah yeeter [sic] ...we have never met...so from the heart i just wanted to say..." said Justin, adding a clip of Sacha Baron Cohen from "Bora" repeatedly saying, "You'll never get this."

This had caused the baby-drama news from last year to resurface again. However, the Bieber did not stop there. In a recent interview, Justin says he had written a song about Mariah Yeater with the lyrics close to the famous song, "Billie Jean".

"She ain't my baby / She ain't my girl," says the lyrics to Justin Bieber's song, "Maria".

"It's about everything I've gone through," explained Bieber, adding, "I've written a song about that whole situation with that girl who said she's having my baby - Mariah Yeater."

With that out of Justin Bieber's chest, surely the 18-year old can now focus on making songs for his "real" fans. Other news apart from the baby-drama song, Justin is also working out with collaboration with Taylor Swift and Ludacris. According to Justin, the diversity of people involved with the collaboration definitely "made sense".

It's a great choice for Justin Bieber but what would really make fans happy is Bieber collaborating with his own girlfriend, Selena Gomez.
