Beyonce is gearing up for her big comeback performance in New Jersey!

Jay-Z's 30-year-old wifey, who gave birth to daughter Blue ivy in January, will be performing a four-night show at the Revel casino beginning tonight.

Check out this behind-the-scenes footage of B! She sure dropped that baby weight awfully fast. Pretty unreal, indeed.

Beyonce has ditched the heavy makeup and couture gowns for a laid-back look while shooting pool.

The 30-year-old, wearing a cropped top and jeans, is sharing some lessons on pool etiquette.

One of our favorite tips ..."psych out your opponent by talking smack." Holla!

Beyonce has her bangin' pre-baby body back!

Jay-Z's wifey hit the red carpet at the 'Schiaparelli And Prada: Impossible Conversations' Costume Institute Gala at the Metropolitan Museum of Art in New York looking beyond gorgeous in an extremely revealing Givenchy Haute Couture gown.

Totally bootylicious. 'Nuff said.

See all of the fabulous fashions at the NYC gala in our gallery below.

Who is the fairest of them all?

The biggest and the brightest stars stepped out for the annual Met Costume Institute Gala in NYC on Monday night, and we're literally drooling over some of their custom couture gowns!

The theme of the night was "Schiaparelli And Prada: Impossible Conversations" and of course, most of the hottest A-listers chose sparkly Prada pieces to wear to the exclusive Ball, which was held at the Metropolitan Museum of Art.

New mom Beyonce left little to the imagination in a see-through black sparkly lace ensemble with purple feather accents by Givenchy, while Liv Tyler looked equally stunning in an all-black design by the same French label -- she's also the face of the brand's perfume line!

Milla Jovovich channeled1920s style in a red Marc Jacobs gown with black accents, while celeb stylist Rachel Zoe, who designed Karolina Kurkova's sequined space-age look, stuck to a clean white fringed dress with a statement necklace from the Rachel Zoe Collection.

Glee star Diana Agron stood out from the crowd in an emerald green chiffon creation by Carolina Herrera, and Diane Kruger's purple Prada gown had such a massive feather train, she needed an extra hand just to carry it!

Which stars rocked the best look at the Met Ball this year?

Beyonce Knowles is a gorgeous new mom, and now she's got the title of the "World's Most Beautiful Woman" to back it up!

The 30-year-old singer, who gave birth to daughter Blue Ivy on January 7, is People magazine's cover girl.

Jay-Z's wifey tells the mag:

"I feel more beautiful than I've ever felt because I've given birth. I have never felt so connected, never felt like I had such a purpose on this earth."

Beyonce adds, "The best thing about having a daughter is having a true legacy," she adds. "The word 'love' means something completely different now."

A true beauty, indeed!

Hot mama Beyonce Knowles showed some leg when we spotted her taking 3-month-old daughter Blue Ivy Carter for a stroll in New York City on Monday afternoon, and the R&B superstar smiled sweetly for X17 photographers.

It's almost as warm on the east coast as it is here in sunny SoCal, so we can't blame Bey for wanting to slip into something a little bit more summery! And that blue nail polish? Any chance her adorable infant was the inspiration behind this bright and bold hue? We're thinking yes!

Taking the night off from diaper duty, Beyonce and Jay-Z made the most of their kid-free evening with a romantic dinner, and a basketball game!

The "Single Ladies" singer looked casual-cool in cheetah-print MC Hammer pants, a big black hat and hot pink heels that definitely made her stand out while sitting courtside at the New York Knicks game, where they played against the Miami Heat at Madison Square Garden, on Sunday night.

While the Carter's team lost the game 85-93, the couple still appeared to be having a blast, and ended the night by partying it up in the city.

Baby Blue Ivy has the coolest parents ever!

Beyonce made sure daughter Blue Ivy was completely safe while stepping out in New York City. What a good mama!

Jay-Z's wifey, who rocked a neutral-colored outfit and blonde wig, kept her baby wrapped up in a stylish blanket. We're loving B's funky shades and killer emerald green pumps.

Nothing but the best for baby Blue!
