Beyonce Reveals Curves In Roberto Cavalli At Jay-Z's 40/40 Anniversary Party (PHOTOS)

Seems as if a little Photoshopping doesn't bother Beyoncé!

Blue Ivy's mom celebrated hubby Jay-Z at the tenth anniversary of the 40/40 Club in New York City on Monday wearing an ethereal white gown which showed off a lot of boob and her toned stomach.

But Queen Bey didn't just wear any old dress; the 31-year-old sported a Roberto Cavalli, the same fashion designer who airbrushed the pop star until she was barely recognizable in a press release last week. (Guess that's water under the bridge!)

Hova seemed to love the dress on his beautiful wife; the rapper was seen with his arm protectively around his baby mama who looked stunning in the floor-length knitted gown which left little to the imagination.

Noticeably absent from the party was Jay-Z's bestie and collaborator, Kanye West, who became a father over the weekend when girlfriend Kim Kardashian gave birth to their first child five weeks early.

Beyoncé congratulated the couple on her Tumblr writing a sweet message to the overjoyed parents.

"Congratulations Kim & Kanye, enjoy this beautiful moment together," Beyonce wrote in a post.

Perhaps all this talk about babies has got Bey and Jay wanting to give Blue Ivy a big brother or sister!
