Where? Filming the X Factor USA season 2 auditions at the Frank Erwin Centre in Texas, 24 May
Bonus info: Britney's first day as an X Factor judge was not without incident as the singer reportedly walked off set after an auditionee performed her song Hold It Against Me. Sources for TMZ suggested her absence was because she was upset by the poor rendition, but Britney took to Twitter to laugh off the speculation: "#Britneywalksoff??? LOL was just taking a little break people. I am having the BEST time!!!"
