Did Fergie have plastic surgery?

There was something different about Fergie - aka Stacy Ferguson – as she made her first official public appearance following her wedding to actor beau Josh Duhamel.The singer looked somehow more picture perfect as she hit the red carpet for 5th Annual Black Eyed Peas Peapod Foundation Benefit Concert held the The Conga Room in L.A.Could she have had a sly nip-tuck in time for her wedding? Or perhaps she is still basking in that post-honeymoon glow.
