Fergie threw herself an early birthday party in celebration of turning 40 over the weekend and invited her close friends and family.

Guests guzzled  down Ferguson Crest wine – a beverage owned by Fergie and her father John Patrick Ferguson.

The ‘Clumsy’ hitmaker doesn’t turn 40 until March 27 but organised an old Hollywood-inspired bash with her close friends and family at her home in Los Angeles on Saturday.

An insider told UsMagazine.com: “Her 40th seemed perfect.”

The 39-year-old star stole the show in a white silk one-shoulder gown, while her guests included her Black Eyed Peas bandmate apl.de.ap and Kelly Osbourne.

The party was held in the blonde beauty’s back garden by her pool, which was decorated with white and red lights, and her friends and family boogied the night away to music, such as tracks from Maroon 5 and Sublime, played by DJ Richie Rich.
