The anniversary parties were big, but the double-headed bash Billboard and Butterflies threw was epic!

The hugely successful Playmates Party returned last night and the Butterflies Babes never looked sexier. usually a bit shy, they were lining up to take photos in their cottontail and bunny ears.

In all, there were more than 250 women shaking their bunny tails on five stages with the sexy Playmates decked out in their stockings, high heels, bowties, bunny ears and tails for this once-a-year occasion that can’t be missed.

Guests enjoyed a buffet of 100 Pizza Mania pizzas, chicken wings and potato wedges plus sexy shows choreographed just for the occasion.

This year’s Billboard and Butterflies parties were packed out by 9 p.m. Check out the photos from last night.
