Model Kate Moss partied with singer Madonna at her 1920s-themed birthday party organised here over the weekend.

The "Frozen" hitmaker turned 56 on Aug 16.

Moss joined Madonna in celebrating her birthday at a lavish party at a private villa here, where the two were pictured cosying up together, reports contactmusic.com.

Madonna posted the photo of herself wearing a beaded black dress next to the model, who was clad in a strappy black gown, on her Instagram account Sunday.

She captioned the image: "Bow down Bitches! #whatitfeelslikeforagirl.(sic)"

Her children -- Lourdes, 17, Rocco, 14, David, 8, and Mercy, 8 -- also attended the birthday bash.
