Liam Gallagher and the mother of his 'love child' have had a fresh court showdown, as she looks for more than £500,000 in child support for their daughter. Liza Ghorbani , who shares 12-year-old daughter Gemma with the Oasis rocker, is hoping to obtain a rise in the yearly payments made by the star for the girl, who is autistic and also has special educational needs. They appeared in court in New York via video link last week. Liza and Gemma live in a rented £3,300-a-month apartment in New York.
