was in the U.K. the other night for their version of "American Idol," something called "The X-Factor." I know this because I have these pictures of her entering before judging the talent that night (which I have to complain are far too tame from what she's regularly been wearing lately). I also know this because I follow her Twats and she explained what a big Cheryl Tweedy fan she was after meeting the singer at the show. For the record, Katy's latest hit single which talks about "California Gurls" is now the number one song in the U.S.A., the U.K. and as she twatted, "OY!" it's number one in Australia now too.
