Justin Bieber has revealed that he's written a song about alleged baby mama Mariah Yeater on his forthcoming LP, Believe.
According to Heatworld.com - who were present at JB's album playback in Notting Hill, London last night (23rd April) - the star has addressed claims made by Yeater last year that Biebs was the father of her son, Tristyn.
When asked about his new record, the 18-year old stated: "I'm going to be talking about everything I'm going through.
"I've written a song about that whole situation with that girl who said she's having my baby - Mariah Yeater. I've written about my mum, loads of things I'm going through."
Last weekend, Justin reignited interest in Yeater's paternity allegations after directing a message on Twitter at Mariah, where he posted: "Dear mariah yeeter (sic)...we have never met...so from the heart i just wanted to say..."
He then attached a YouTube clip of Sacha Baron Cohen's character Borat saying: "You will never get this", over and over again.
As well as speaking about Yeater, Justin - who recently released new single Boyfriend in the UK - also admitted he believes he's pretty good with the ladies.
He told Heat: "Yeah, I think I'm a great boyfriend because you have to be honest and patient with girls... 'Cause sometimes they can give you a headache.
"If you spend time doing things from the heart, then girls like that kinda thing. Presents are just something from the store," - lucky Selena Gomez!
Bieber also ruled out a collaboration with pals The Wanted and One Direction, saying he has "no plans" to work with the UK boybands yet.
Never Say Never, Justin...
