Hey, haters: Leave Kim Kardashian alone! That's the message that Kanye West shared with the A-list list attendees inside New York's Metropolitan Museum of Art as he performed a new song during the annual Costume Institute gala. With his 7-months-pregnant girlfriend looking on, the rapper, 35, debuted a track that was "an ode to Kim ... about how awesome she is," an insider explained to Us. "The audience was jamming to it. Kim was smiling and loving it."

Another fan? Supermodel Coco Rocha, who shared a Vine of West's performance. "Kanye telling Kim not to worry what anyone says that she's awesome. Quite touching really."

By all accounts, Kardashian, 32, had a fantastic night. The reality star emphasized her baby bump in a Givenchy by Riccardo Tisci gown: A long, floral print gown with high slit plus matching, built-in gloves and sandals. Sharing her own snapshot of West's performance, she returned the compliment: "Baby you're AWESOME." Among other instagram snapshots, Kardashian shared a huge group shot, where the famous couple are surrounded by other revelers (some of them flipping off the camera playfully). "Night at the Musuem," Kardashian wrote in lieu of a caption.
