Fergie celebrated her 37th birthday at 1 Oak Nightclub on Friday in Las Vegas, Nevada.

She wore a Givenchy Resort 2012 multi-coloured jersey dress with a birds of paradise and iris flower print.

The singer accessorized her vibrant dress with a small black clutch and pointed black pumps from her own shoe collection.

Voluminous wavy blonde locks and a nude lip colour completed her look.

It’s a shame that no one told the birthday girl that La La Anthony had worn the same dress the week before.
