The extravagant affair took place at the Versace mansion in Miami where Queen Bey, 32, was clad head to toe in the designer's brand, wearing a racy animal-printed top that tied at the waist, showing off her abs and cleavage. She paired the top with a black and gold silk robe with animals all over it and a pair of tiny matching shorts and a gold-chain belt.
Her rapper hubby of almost six years, Jay Z, 44, looked suave in a baroque-printed royal blue blazer and their daughter Blue Ivy Carter, now 2, wore a metallic silver dress with a matching crown.
Beyonce's former Destiny's Child bandmates, Michelle Williams and Kelly Rowland, attended the bash, and X Factor judge Rowland, 32, brought her new fiancé Tim Weatherspoon.
Other celebs in attendance were Spike Lee, Adrienne Bailon, The Dream, model Joan Smalls, and Italian designer Riccardo Tisci -- who is the creative director for Givenchy and also selected Kim Kardashian's 2013 floral Met Gala gown when she was pregnant.
Most of Beyonce's tumblr shots appear to be candid, with the guests dancing around the party. She also shared a shot with her rapper hubby riding on a moped and later hitting the dance floor to bust a move.
Beyonce recently traveled down to New Orleans to throw her mother, Tina Knowles, a 60th birthday party along with her sister Solange Knowles. The costume party featured plenty of celebrities and a live band.
The "Grown Woman" singer had plenty to celebrate these days. Her surprise self-titled fifth studio album smashed iTunes records for digital album sales when she dropped it on Dec. 13.
