Justin Bieber plays "ping pong" to take his mind off of fatherhood claims, a friend says.
Mariah Yeater, 20, filed a paternity lawsuit against 17-year-old Bieber claiming that her three-month-old son is the superstar's biological child.
Bieber has completely rejected the idea, stating that Yeater's claims are false.
To take his mind off of the stress of the situation, Bieber has been relying on the comfort and advice of his girlfriend Selena Gomez and his close friend Tay James.
"[Justin] never even met the woman who claims she's had his baby," James told British newspaper The Mirror.
