"All the rumors...the gossip....I'm gonna focus on the positives....the music."
This was the tweet from Justin Bieber that followed allegations that the teen idol has fathered a baby.
Twenty-year-old fan Mariah Yeater has been pictured with her five-month-old son Tristyn Anthony Markhouse Yeater.
She has filed a paternity law suit claiming 17-year-old Justin fathered the baby.
Mariah claims he is the result of a tryst the pair had backstage after they met at one of his concerts.
Justin's representatives have denied the claims, telling Radar Online: "While we haven't yet seen the lawsuit, it's sad that someone would fabricate malicious, defamatory, and demonstrably false claims.
"We will vigorously pursue all available legal remedies to defend and protect Justin against these allegations."
