The songstress (real name Stacy Ann Ferguson) is expecting her first child with husband Josh Duhamel and judging by this new picture, it might not be long until their tiny tot arrives!
On Sunday (11 August), Fergie uploaded a cute snap of herself hanging out with two of her longtime BEP bandmates, wearing a figure hugging pink and black dress that accentuated her bump.
Although a due date for her baby hasn't been confirmed, it seems as if the 38-year-old could be heading to the delivery room soon. But that hasn't stopped her from accessorising her stylish maternity outfit with a pair of killer metal capped heels!
Beside the photo, Fergie revealed that will and apl.de.ap are already being considered as uncles to her unborn child. She also remarked that the trio were missing their fourth bandmate, Taboo.
She captioned the picture: "#UncleLove @iamwill & @apldeap. Miss u @tabooexperience".
Last month, the fun-loving pop star celebrated her pregnancy with an elaborate baby shower - or as she dubbed it, a "gayby shower"!
Celebs such as Kelly Osbourne, Jamie Foxx and N'Sync-er Lance Bass all came out to party with Fergie and Josh at the SLS Hotel in LA, where they reportedly enjoyed a four-tiered cake and "Ferg-arita" cocktails.
And given that the happy showbiz couple have confirmed they are expecting a son, the colour theme of the bash was of course baby blue. Aww!
