(Cover) - EN Showbiz - Justin Bieber plays "ping pong" to take his mind off of fatherhood claims.

Mariah Yeater, who is 20-years-old, filed a paternity lawsuit against 17-year-old Justin claiming that her three-month-old son is the superstar's biological child.

Justin has completely rejected the idea, stating that Mariah's claims are false.

To take his mind off of the stress of the situation, Justin 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," Tay told British newspaper The Mirror. "[Selena and I] try to take Justin's mind off it by playing ping pong. He loves it."

Justin has an abundance of support from his loved ones amidst this crisis. His sweetheart Selena is doing everything she can cheer him up.

"She is supporting him through this," Tay said. "She's his rock."

Mariah is demanding that the Baby singer take a paternity test and award her child support.

The California woman claims that she only met Justin once but that their alleged liaison at one of his concerts in October 2010 led to her getting pregnant.

The child, Trystyn Anthony Markhouse Yeater was born back in July.

A date has been set in December for the hearing of her lawsuit. (C) Cover Media
