MET Gala 2014 event was one of the most fashionable event for the Hollywoood A-listers. The event concluded with MET Gala after party where many celebrities chose to change into something more informal and let down there hair to dance and get drunk. The official MET Gala 2014 after party was at the Boom Boom Room at the Standard but Bad Girl Rihanna too hosted her very own after party, which lasted much longer and had more celebs enjoying.

Rihanna decided to expose her butt in a golden gown at her own bash. The singer, who is very comfortable showing off her skin, also showed off some side boob in that dress. Check out Rihanna's butt-revealing picture here.

Rihanna and nudity go a long way. The singer's Instagram account was deleted sometime back after she posted her completely nude pictures there. Rihanna was warned by the photo sharing Web site to take the nudes down but she chose not to. She has even posted her nude pics on Twitter too.

Rihanna's bash was notably attended by Kristen Stewart (who reportedly was not invited but crashed in), Leonardo DiCaprio and his girlfriend Tony Garrn, singer Selena Gomez, Suki Waterhouse, John Legend and wife Chrissy Teigen, Seth Meyers and wife Alexi Ashe, Janelle Monae and Naomi Watts.

Also present at RiRi's after party were Grammy Award winner actor from "12 Years a Slave" Chiwetel Ejiofor, Jessica Alba and husband Cash Warren, Ellen Pompeo from "Grey's Anatomy" and Kristen Wiig.

But Rihanna's on and off boyfriend Drake decided to skip the star studded gala party of his girlfriend. Like RiRi, many other celebs too opted to change their outfits. Kristen Stewart decided to ditch her metallic black gown and change into her trademark casual look of denims, canvas shoes and a matching blue top. Kendall Jenner changed her white gown to a red party dress and enjoyed the party with her friends Taylor Swift and Selena Gomez. Victoria's secret model Cara Delevingne too changed into something really as comfortable as black denims and a jacket over her MET Gala's glamorous outfit.
