( Rolling Stone ) -- At a listening party in London last night , Justin Bieber told reporters that one of the many new songs that could appear on his upcoming album , `` Believe , '' was about Mariah Yeater , the woman who falsely accused him of fathering her child , the BBC reports . According to the BBC , while talking about his inspiration , Bieber said he 'd written `` songs like that girl -- Mariah Yeater -- who said she was going to have my baby . '' The singer added , `` I wrote about that situation . '' Last November , Yeater claimed that she and Bieber had sex backstage following a show in Los Angeles , and that he was the father of her then-three month old baby boy . While the case was dropped a few weeks after , Bieber still took a paternity test that proved he was not the father . In London , Bieber also said he 'd recorded 40 songs for the record , and of the various collaborations ( ranging from Taylor Swift to Drake to Kanye West ) he said , `` It 's so cool to do different styles and step out of my comfort zone . '' `` Every song has a piece of me , it 's hard to pick , '' Bieber said `` I wrote almost all of them or co-wrote them . '' See the full article at RollingStone.com .
