(popmusiclife) The judge hit The X Factor stage Thursday night. Former Pussycat Doll Nicole Sherzinger took her turn at center stage on the semi-final results show this week, where she performed a new song, "Pretty."The track was billed as being from her forthcoming solo debut album "Killer Love" – which is out in Europe but whose US release keeps getting pushed back. The record was set for a November 15 release, but will now come out sometime in 2012.
The North American version will have a different song list than the European issue, for some reason. Video of her performance here.
