Singer Fergie and her husband Josh Duhamel were joined by celebrity friends including Adam Lambert, Kelly Osbourne and Julianne Hough as they celebrated the impending birth of their child on Sunday (28Jul13).

The parents-to-be threw a lavish baby shower at the SLS Hotel in Los Angeles with the Black Eyed Peas star taking to the mic at the start of the bash to announce, "It's my baby boy's first party!"

Family and friends, including Lance Bass, Gabriel Aubry and Matthew Mosshart, sipped on Fergie's own Ferguson wine and specially created cocktails named in honour of the pregnant star - The Hot Mamma - while tucking into a four-tiered cake.

The singer announced her baby news in February this year (13).
