The 40-year-old supermodel joined the 'Material Girl' singer in celebrating her 56th birthday at a lavish 1920s-themed celebration in a private villa in Cannes, France, where the pair were pictured getting themselves in a bit of a flap (gerrit?! Sorry, it's Monday).
Madonna posted the photo of herself wearing a beaded black dress next to the model on her Instagram account yesterday. She captioned the image "Bow down Bitches! #whatitfeelslikeforagirl" 'cause she's classy like that.
The singer also shared a shot of some jovial partygoers posing in front of giant 'M' and intertwined with pink feather boas, who were clearly enjoying their evening.
'House of M! House of Fun! La Vie en Rose! #unapologeticbirthdaybitch.'
Madonna - who was joined the event on Saturday by her four children, Lourdes, 17, Rocco, 14, David, eight, and Mercy, also eight - also shared a picture of her youngest son looking dapper in a black tuxedo.
He didn't have anything shielding his eyes, but sure he's probably seen it all before #willsomebodypleasethinkofthechildren!
