Dressed in her finest flapper couture to attend a birthday bash this weekend, a dazzling Kim Kardashian teased followers on Twitter with her new, old-Hollywood look.

"All glammed up for a fun 1920s themed party!" she tweeted.

The guest of honor was Eva Longoria, according to RadarOnline.com. The 'Desperate Housewives' star threw herself a lavish 36th birthday celebration for friends, amid reports that she's getting serious with her younger beau, Eduardo (who happens to be the 25-year-old brother of Penelope Cruz). Longoria's divorce from NBA star Tony Parker was finalized in January.
