Fergie and husband Josh Duhamel had some fun in the sun to celebrate another year of marriage, and their vacation pictures could not be any cuter.

"8 years!" Duhamel posted on Tuesday, along with a picture of the happy couple on the beach with their 3-year-old son, Axl. "Love you babe."

That same day, Fergie posted a shot of her own, featuring just her and her man, writing, "Happy 8th anniversary to my bae."

The 41-year-old "M.I.L.F.$" singer and the 44-year-old Transformers actor tied the knot in 2009 during a fairy-tale ceremony at the Church Estates Vineyards in Malibu.
