*The woman who accused teenage singer Justin Bieber of fathering her baby has dropped her paternity lawsuit.

Single mother Mariah Yeater quietly withdrew her request for a paternity test and child support last week, according to reports.

The 20-year-old made instant headlines earlier this month when she went public with claims that Biebs knocked her up last year after a romp backstage at his Los Angeles concert.

Yeater told reporters she had evidence proving Bieber was the father of her four-month-old son Tristyn, but the singer vehemently denied her allegations.

The star agreed to take to a DNA test to disprove her story while his lawyers threatened to take legal action to “defend and protect” the singer.
