Teen idol Justin Bieber, whose testicles descended earlier this year, sounded a hot mess during last night’s telecast of ABC’s ‘Dancing With the Stars’ results show.

Weighing heavily on his mind must have been the paternity suit filed by a 20-year-old California Stan accusing him of fathering her 3-month-old baby boy.

Mariah Yeater was paid an undisclosed sum of money to tell her story to Star Magazine, which features Mariah and her son on the cover this week. Yeater filed her paternity suit on Oct. 31 in LA. She said the sexual tryst with Bieber occurred on a shelf in a bathroom at the Staples Center following a concert last year.

Her son, Tristyn Anthony Markhouse Yeater, was born on July 6 — exactly 36 weeks and two days after the alleged sexual encounter with Bieber.

In a legal statement, sworn under penalty of perjury, Yeater told a California court that Bieber propositioned her on October 25 of last year, when she was 19 after his concert and at L.A.’s Staples Center.

According to U.S. website Radar Online, Yeater told a judge: “When I later realized I was pregnant with Justin Bieber’s baby, I tried to contact him through his representatives but no one ever called me back.”

She added: “On July 6, 2011, I gave birth to a baby boy. That was exactly 36 weeks and two days after the sexual encounter with Justin Bieber.”

“Based upon the timing as well as the fact there were no other possible men that I had sex with that could be the father of this baby, I believe that Justin Bieber is in fact the father of my baby.”
