Fergie traded in her workout gear for a cute preppy ensemble during a trip to London this week. She may be in the city that inspired her first solo hit, but she's got a new song to celebrate while overseas -- Glamorous hit No. 1 on the Billboard Hot 100 singles chart. The song has been in and out of the top 10 for the past two months, but it was the 166,000 downloads in one week that helped finally secure the top spot! With this kind of success, Fergie should be in limousines and boogie scenes for a long time to come.
