Liam Gallagher is being sued in a New York court by a woman who claims he is the father of her one-year-old daughter, the New York Post reports.
A spokesman for the British rock star would not comment on the tabloid's claims, but said that lawyers would be taking action over the report.
The Post said in its online edition that the former Oasis frontman had been asked to provide financial support for the toddler in a confidential suit currently before the Manhattan Family Court.
It said the case had been reviewed by magistrate Matthew Troy on Friday at a preliminary hearing listed as "Anonymous v Anonymous" and then adjourned until later this month.
The woman involved was said to be in her 30s and to specialise in interviewing celebrities.
The Post's story follows a report in Britain's Sun newspaper on Saturday which claimed an unidentified British rock star was being sued for US$3 million by the mother of an alleged American love child.
Gallagher, 40, is married to former All Saints star Nicole Appleton.
He has three children, a daughter who was the result of an extra-marital affair during his first marriage to actress Patsy Kensit, and two sons - one with Kensit and one with Appleton.
He is currently the lead singer of Beady Eye, a group he formed after the 2009 break-up of Oasis and his estrangement from brother Noel.
He claims to have turned his back on the rock and roll lifestyle for which he was once famous.
