Gisele Bundchen
let her hair down at Saturday night’s Spring Fling party. The supermodel took to the floor and was “dancing energetically, she was really going for it,” a source said. Another witness at the party hosted by
Harry Josh and
Nur Khan — dubbed the “unofficial pre-party” for last night’s Costume Institute Gala — told us, “
Fergie
danced a few feet away from Gisele, and the two greeted each other before the real dancing started. Fergie was having a blast, surrounded by a group of guys who were
Beyoncé
‘s dancers. The guys started having a dance-off, competing to impress Fergie. Her bodyguard pushed away a few overzealous dancers.” Later, Fergie and her crew headed to Splash and closed the place down. Also at the Spring Fling at Hiro Ballroom were
Zoe Saldana
,
Jason Statham
,
Mickey Rourke and
Will Smith
, who arrived with
Jay-Z
at about midnight. The two were ushered to a corner booth, where they held court with several glamazons.
