Gathering the whole gang to help out the family business, Fergie, Josh Duhamel, and their baby boy took a trip to Ferguson Estate vineyard this past weekend.

Located in Santa Barbara County, California, the vineyard is the source of Ferguson Crest wine, owned by the Black Eyed Peas frontwoman and her father, Pat.

Sharing a photo of herself with bunches of grapes and her hubby clutching some clippers, the 38-year-old star tweeted, "It'z harvest day at @fergusoncrest."

Later, Fergie posted an adorable photo of baby Axl in the arms of her dad with the caption, "Grampas favorite bundle of grapes in the vineyard."
