Nick Cannon with the Butterfly Girls at Chateau Gardens' grand opening.

Nick Cannon and Holly Madison hosted an elaborate party for the first night of Chateau Gardens’ grand opening celebration at Paris Las Vegas last night.

The new rooftop nightclub under the Eiffel Tower was a befitting backdrop for Cannon’s 31st birthday with the launch of Chateau Gardens’ signature event, “Butterfly.” Cannon’s beautiful bride was with him in spirit as he was presented with a blue butterfly cake, approved by Mariah Carey herself while framed by two mystical butterflies as he enjoyed the gorgeous view of the Bellagio Fountains. The DJ booth welcomed Cannon with images of brilliant butterflies on the 100-plus-square-foot video screen.

Madison was drop-dead gorgeous, dressed head-to-toe in a flora and fauna ensemble she put together especially for the grand opening of Chateau Gardens. Wearing the latest black stiletto Christian Louboutin spider web design and floral Bottega Veneta dress, the former “Girl Next Door” showed why she has become known as the Strip’s signature fashionista. Celebrating the seasons one and two DVD releases of her hit namesake show on E!, Madison danced in her private VIP booth with her boy-BFF and Peepshow and “Holly’s World” co-star Josh Strickland.
