(Cover) - EN Showbiz - Rihanna "didn't scrimp on detail" at her prom party in London at the weekend.

The songstress hosted an 80s-themed bash in the British capital to celebrate the end of her Loud series of shows at the O2 Arena.

Rihanna dressed as Madonna from her Like A Virgin promo as she entertained guests in the city centre.

"Rihanna didn't scrimp on detail. She walked around the hall dressed like Madonna and put wrist corsages on all the girls," a source told British newspaper The Sun.

"When she helped serve the dinner, she was teasing the guests with the zip on her dress."

Rihanna is famed for her provocative personality. The 23-year-old beauty incorporated some of her naughty nature into the celebratory bash.

"Of course it wasn't a dry affair. There was an array of cocktails on offer called Sex On The Beach, Porn Star and Bosom," the source added.

Rihanna took to her Twitter page earlier this week to gush about the party. The Barbadian star loved donning her Madonna-inspired garb.

"We just had our end of year/tour Christmas party!!!! We turned it into an 80's prom, since I've never had one! It was sooo much FUN!!!!" she wrote.

"I'm decked out in lace, sequins, a giant bow, and hair spray (sic)!!!!!" (C) Cover Media
