Paula Abdul has dismissed reports of a feud with fellow American Idol judge Kara Dioguardi - insisting the new recruit is like a “sister”.

Abdul, who has been with the show since its first series in 2002, was rumoured to be against the decision to hire DioGuardi for the new season of the hit US talent show, which kicks off next year.

But the Straight Up hitmaker is adamant she harbours no animosity toward DioGuardi.
