Other guests included another one of our Bellyitch Bumpwatch alums, Kelly Rowland, Tracee Ellis Ross and Janelle Monáe.
“There were lot of A-list stars in attendance, a source told E! “Beyoncé was sitting down in a beautiful white long dress, and Jay Z stood by her side, head bobbing to the music. Solange was very hospitable and chatted with all her guests.”
The source said that Bey spent most of the night sitting down but was kind and gracious to everyone who came up to her.
Bey and her husband Jay-Z are expecting their second and third child, a pair of twin. They are parents to 5-year old daughter Blue Ivy, who they welcomed on January 7, 2012.
