Pink arrives at the BBC Radio Studios in West London (Dec. 5, 2012).

*After performing on “The X Factor UK” over the weekend, Pink rolled through BBC Radio today (Dec. 5) and gave her British fans an unexpected treat – a performance of Alicia Keys’ hit single “Girl On Fire.”

2012 has been a great year for both Alicia and Alecia, Pink’s real name.  The rocker’s sixth studio album, “The Truth About Love,” came out in September. Both ladies released their first albums since becoming new moms, and both debuted at the top of the charts with their respective releases.
