She's always the first to poke fun at herself and this was no different as Vicky made quite an entrance on the show dressed as the Duchess in a dark brown wig and the same famous navy dress Kate wore to announce her engagement in 2010.
Vicky even arrived on the arm of a Prince William lookalike holding an adorable (and strangely convincing) Prince George lookalike!
Vicky wasn't the only celeb joining in the royal celebrations as her hilarious Instagram snap shows. Taking on the role of the birthday girl herself, was former Birds of a Feather star Linda Robson who looked slightly less convincing as the Queen in her grey wig, ivory dress, sash and velvet cape.
"Me and the grandmother in law... Playing k-middy and the queen today on @loosewomen with this sort!!! Love you @lindarobson58!!!" said Vicky.
We assume the topless fellas in the background were playing the role of the Queen's guards. As you do!
The closest Vicky has come to blue blood in the past is when she briefly dated Essex posh boy, and former MIC Lothario, Spencer Matthews earlier this year. Spencer's brother James is dating Kate's sister Pippa and Vicky said at the time: "I've not met Pippa yet, but I'd be so nervous if I was at an event with her and Kate.
"Spencer won't introduce us because I'm common as muck. He'd be worried I'd get her out on the lash with me. Also, I'd probably run off with Prince Harry if I met him. He's my dream man."
Ours too, Vic!
