The 20-year-old California woman who claimed that Justin Bieber was her child's father dropped her paternity lawsuit against the teen sensation, TMZ reported Wednesday.

Mariah Yeater claimed she had sex with the star backstage at one of his concerts in Los Angeles when she was 19 and requested that Bieber, now 17, take a paternity test.

The lawsuit was quietly dropped last week, and Yeater's lawyers have withdrawn from the case, according to the report.

Bieber has denied the allegations and was reportedly prepared to take a paternity test to prove he is not the baby's father.

Yeater initially filed the suit earlier this month. The 20-year-old woman was on food stamps when she acquired front row tickets to Bieber's Los Angeles concert last year. She said she was later plucked from the crowd by security to meet the singer backstage.

    Bieber, however, claims he never met the woman.

    Yeater has been unemployed since March 15, 2011 and over the last 12 months, claimed an average paycheck of $125. She also gets $500 a month in public assistance.

    She claimed the birth of her baby, born July 6, cost $25,000.

    Yeater originally told an ex-boyfriend that he -- and not Bieber -- was the father of her baby, the New York Post reported earlier this month.

    She could face serious legal ramifications for the claims against Bieber, experts say.

    "If Ms.Yeater is making up these allegations and Justin Bieber is able to prove that in court by winning the case that she has filed, she may be liable for malicious prosecution under California law,” explained entertainment defamation attorney, Mitchell Langberg of Brownstein/Hyatt/Farber/Scheck LLP. “If that happens, she and her lawyers could be responsible to pay Bieber's attorneys' fees and other damages, but not for harm to his reputation.

    "A libel or slander suit can almost never be based upon what someone says in a complaint.  In fact, if he sues her for defamation, under California law he might end up being responsible to pay her attorney's fees. On the other hand, if she is making these same allegations directly to the press and Bieber can prove that they are false -- and that she knew it -- he may have a valid defamation claim."
