Justin Bieber will take a paternity* test and then he plans to sue the woman who has filed a paternity suit against him, a representative for the teen pop star said on Monday.

    Matthew Hiltzik said the 17-year-old singer will take a paternity test when he returns to the United States within the next two weeks. He also said Bieber’s team plans to “vigorously pursue all available legal remedies to protect Justin.”

    Mariah Yeater filed the paternity suit last week in San Diego Superior Court. She said she had just turned 19 when she and Bieber, then 16, had a brief sexual encounter after one of the singer’s concerts last fall in a backstage bathroom at Los Angeles’ Staples Center.

    Bieber has said he’s never met Yeater and has denied allegations that he fathered Yeater’s 3-month-old child.

    The singer was in London on Monday to switch on the Christmas lights at the city’s two biggest shopping malls.

    Thousands of young and mostly female fans waited hours for Bieber to appear. Bieber traveled the 12 miles between the malls by helicopter.

    The star, who won two prizes at Sunday’s MTV Europe Music Awards in Belfast, told fans that his favorite thing about London was “all the girls.”

    Bieber said backstage on Monday that despite the ups and downs, he was grateful to his fans.

    “I take it with a grain of salt. It’s been incredible, my fans are amazing and I wouldn’t have it any other way,” he said.(SD-Agencies)
