Liam Gallagher is suing the New York Post over their allegation that he may have fathered a child with an American journalist. Representatives for the Beady Eye frontman said they are pursuing legal action against the newspaper, which ran the headline "Rocker Liam Gallagher in 'love child' suit".

According to yesterday's Post article, Gallagher is being sued in Manhattan family court by a woman who "specialises in interviewing celebrities". The plaintiff is apparently seeking $3m and is "considering undergoing DNA tests" to strengthen her case. Although Friday's legal hearing was not listed publicly, the Post reports that it took place with magistrate Matthew Troy under the heading "Anonymous v Anonymous", and will continue later this month.

At first, neither Gallagher or Raoul Felder and Bill Beslow – the lawyers said to be representing the parties – responded to the Post article. But by the end of yesterday, the singer's British spokesman confirmed that he will be "pursuing legal action" against the tabloid. "We are not going to comment on gossip," they added.

Historically, Gallagher has not been afraid of using the courts to battle accusations he denies. He sued the Guardian in 2009, for an incorrect report that he "stormed out" of an Oasis gig. Then, two years ago, he filed a high court complaint against his brother: Noel Gallagher had claimed that Liam once cancelled an Oasis gig because he "had a hangover". "That is a lie and I want Oasis fans and others who were at V to know the truth," Liam said in a statement. That case was eventually dropped after Noel admitted his brother had been suffering from laryngitis.

Gallagher is a father of three children: one with his first wife, Patsy Kensit, another with Lisa Moorish, and a third with his long-time partner Nicole Appleton. He and Appleton married in 2009.
