Justin Bieber now has one less “baby, baby, baby” on his mind.

The 20-year-old woman who has accused the 17-year-old pop singer of being the father of her 4-month-old son has reportedly dropped her paternity lawsuit.

Celebrity gossip website TMZ reports Mariah Yeater “quietly dismissed” her lawsuit against Bieber last week.  The site also reports Yeater’s attorneys, Lance Rogers and Matt Pare, have resigned as well.

The paternity suit Yeater filed against Bieber last month claimed a minutes-long tryst between the two in a backstage bathroom at the Staples Center in Los Angeles following a concert in October 2010 resulted in the birth of her son Tristyn Anthony Markhouse Yeater this July.

Yeater, who was 19 at the time the alleged tryst took place, had been very public with her claim, appearing on “The Insider” earlier this month.  She claimed then the “Never Say Never” star, who was 16 at the time, was “aggressive” and refused to wear a condom the night she said he got her pregnant.

“This is a legitimate claim by a woman who wants to know the father of her new baby,” Yeater’s lawyer said at the time.

Bieber denied the allegations from the start, claiming the story was “completely made up” and that he had never even met Yeater.

After Yeater’s appearance on “The Insider,” Bieber’s legal team hit back and promised their client would take a DNA test upon his return from Europe, where he’s been touring and publicizing his new release, alongside longtime girlfriend and fellow pop star Selena Gomez.

Bieber’s team also gave notice they planned to file a lawsuit against Yeater once the DNA test proved their client’s innocence, they said.

Neither Yeater’s nor Bieber’s attorneys responded to requests for comment from ABC News.

Bieber has taken to Twitter to address the controversy, and thank fans for their support, writing, “Even through all the crap and lies…my fans have been there for me…thanks to everyone who supports me.  Much appreciated.”

Yeater, meanwhile, faces a bench trial next month on a misdemeanor battery charge filed against her last December claiming she slapped her 18-year-old ex-boyfriend, the same ex-boyfriend whom she earlier accused of fathering the baby she then said was Bieber’s.

The charge could leave her facing six months in jail and a $1,000 fine.
