Less than a week after 20-year-old Mariah Yeater accused Justin Bieber of possibly being her baby’s father, the 17-year-old star and his team are striking back, and hard. According to TMZ, which spoke to sources close to the teen heartthrob, his lawyers have already informed Yeater’s that in two weeks, when he’s back from his European tour, the Biebs will take a paternity test. Then, after his good name (though maybe not his virginity) is vindicated, he will sue her. Not surprising, given the money and power behind the Bieber apparatus, Yeater’s lawyers were described as “nervous†upon hearing news of possible legal action.
