A $9 million lawsuit against Justin Bieber has been dismissed.

The 'As Long As You Love Me' singer - who recently split from his girlfriend of two years Selena Gomez - has scored a huge victory after a woman, who took legal action accusing him being responsible for her eardrum bursting at his concert in Portland, Oregon on July 14, 2010, decided not to pursue the case any further.

A source told gossip website TMZ.com that Stacey Betts filed documents last week asking to dismiss her case, in which she was seeking $9 million in damages, because she didn't have a lawyer and felt it was impossible to move forward with legal proceedings.

But Stacey still believes in the merits of her case, which she filed after attending a concert with her daughter in 2010 and claimed the 18-year-old Canadian singer incited his fans into such a frenzy that the volume of their screams left her with permanent hearing damage.

The case was dismissed on the same day as Stacey filed her documents.

Meanwhile, Justin's mother has attracted attention after it was announced she has produced a new anti-abortion movie.

The singer's mother Pattie Mallette - who gave birth to the popstar when she was 19 and was sexually abused as a child herself - is an executive producer for the upcoming anti-abortion short film 'Crescendo,' which she hopes will raise $10 million for pregnancy centres worldwide.

The 37-year-old author claims her sexual abuse and addiction led to her getting pregnant at a young age and she hopes the film will educate young girls and help those in similar situations to realise that they are not alone.

The movie maker will also embark on a mini tour and will appear at some of the clinics as part of an effort to raise awareness.
