Beyonce let the whole world know that she is not pregnant by donning a midriff-baring outfit at Kanye West's 36th birthday party in New York City on Saturday. 

The 31-year-old "Grown Women" singer, who just did a new L'Oreal Infallible lipstick commercial, rocked a black-and-white striped long sleeve top and cropped skirt combo at Ms. Lily's, according to US Weekly. She showed everyone that by flaunting her toned abs and skin-tight stripes, she is indeed healed from the media frenzy, gossip and recent public character attacks.

To finish the look, Jay-Z's wife paired the hybrid number with bold orange heels, a charcoal Fedora hat and sunglasses. She left her blonde locks out and flowing.

B joined her husband, Jay-Z, Nas and West, who partied solo without pregnant girlfriend, Kim Kardashian, according to TMZ.

For obvious reasons, Kardashian is Los Angeles bound and unable to travel because of her pregnancy. She recently took her last trip to Paris, France before getting ready to give birth soon.

West was in NYC to headline the Governors Ball on Sunday.

While Kimye are waiting for the arrival of their bundle of joy next month, B and Jay seem to be just enjoying life with 17-months-old daughter, Blue Ivy. 

Recently, B took and posted a cute photo with her photogenic daughter while relaxing and cuddling in a hot tub on Tumblr, according to Just Jared. Blue rested on B's chest in a striped swimsuit and bow in her hair while B donned dark sunglasses, earrings and a turban wrap on her head.

The Grammy winner looked peacefully off into the distance, indicating that she is enjoying her brief break from the Ms. Carter World Tour.
