Fergie: Happy Birthday Avon!

Fergie sprays a spritz of her new perfume Outspoken Intense at the Believe World Tour held at Madison Square Garden on Wednesday (April 6) in New York City.

The 36-year-old singer sang “Happy Birthday” to cosmetics company Avon to celebrate its 125th anniversary.

At the preview event, Fergie unveiled the new perfume, which will hit stores in late summer 2011.

Fergie had plenty of costume changes throughout the afternoon. She wore three different outfits to the event!

FYI: Fergie rocked “Beenie” pumps, “Bold” slingbacks, and “Tremble” sandals from Fergie Footwear.
