Katy Perry is an American born singer and song writer that is closely associated with fellow Disney stars Miley Cyrus, Selena Gomez, and the Jonas Brothers. Katy Perry recently announced her engagement to Russell Brand, and maybe pregnant.
Nabbed as the special celebrity guest performer for the UK talent competition's latest episode, Katy Perry was the main attraction during Sunday night's (October 16) installment of "The X Factor".
Rocking her fresh pink coif, the "Teenage Dream" darling hopped out of a chauffeured ride upon arrival to London's Spring Studios, tweeting prior to show's kickoff, "UK! I'm on X FACTOR tonight! I'll be singing one of my favorite songs... Tune in! It starts @ 8PM!"
