Queen Bey became a bumblebee!

Due with her first child in February, Beyonce didn't let a growing baby bump interfere with her Halloween plans.

Making the most of her curves and expanding belly, the singer, 30, dressed as a bumblebee -- a fuzzy, structured costume and antennae headband -- at Monday's Gypsy Halloween bash hosted by Anja Rubik and her pal Kanye West.

With such celebs as Naomi Campbell, Tyson Beckford and Russell Simmons also in attendance, the "Love on Top" singer showed up for the bash with a small group of gal pals and a watchful security guard. Although Jay-Z's world-famous wife stayed in her seat for most of the party, she sang and danced from her chair -- vigorously! -- to tunes from DJ Khaled, T Pain, Snoop Dogg and other hip hop stars.

When Jay-Z and Kanye's hit "Ni*** in Paris" came on, the diva even orchestrated a few hand-flip dance moves a la "Single Ladies!"
