Kim Kardashian can scratch one major, major celebrity meeting off of her to-do list: Madonna. Both Kardashian, 32, and the pop superstar, 54, were among the sea of A-list celebrities inside the Metropolitan Museum of Art for the annual Costume Institute Gala. Per Instagram, it was apparently the first time the pregnant reality star has met the Material Girl, who once collaborated with Kardashian's beau Kanye West on her 2008 Hard Candy album.

"When we first MET Madonna," an excited Kardashian writes beneath a photo in which Madonna (clad in a studded Givenchy jacket and wearing a black bob wig) puts her gloved hand over Kardashian's shoulder. (The heavily pregnant Kardashian interpreted the night's punk theme with a floral Givenchy gown and matching gloves and sandals.)

Two other music divas in Kardashian's mix? Beyonce and Solange Knowles. "Met Life Beyonce Solange Knowles," Kardashian wrote in another pic, in which she hangs with Beyonce, 32, and Solange, 26.

Beyonce, who made the second-to-last red carpet appearance before Madonna, is well acquainted with Kardashian, thanks to husband Jay-Z's close friendship and multiples projects with West, 35.
