The 'You Da One' singer helped serve dinner and entertained guests looking the spitting image of The Queen of Pop.
Rihanna hosted a private party in London on Sunday (18th December) and dressed up as Madonna from her 'Like A Virgin' video.
The 'We Found Love' singer had just arrived in the capital in preparation for her final three shows of her 'Loud' tour and decided to put on a prom party for her friends.
A source told The Sun that the Bajan star went all out with her attire and was also seen serving her guests and teasing them with her dress.
"Rihanna didn't scrimp on detail. She walked around the hall dressed like Madonna and put wrist corsages on all the girls," they said.
"When she helped serve the dinner, she was teasing the guests with the zip on her dress."
Rihanna has two dates remaining on her 'Loud' tour which finishes tomorrow evening at London's O2 Arena after a headline performance at the same venue tonight.
The shows are also being filmed for a new live concert DVD which Rihanna will release sometime in the new year.
Meanwhile, behind the scenes footage has emerged today form Ri-Ri's forthcoming music video for new single 'You Da One'.
