The Met Gala was full of gorgeous couples [1] on Monday night, but there were also a handful of celebrities who turned the event into their own personal girls' night. While Lena Dunham celebrated the end of Girls with showrunner Jenni Konner, stars like Naomi Watts [2], Stella McCartney, and Kate Hudson [3] served up some serious fierceness on the red carpet, not to mention all the sweet mother-daughter [4] and sibling moments [5]. Apparently it was ladies' night at the Metropolitan Museum of Art and we didn't get the memo.

Frances Bean Cobain and Courtney Love enjoyed some mother-daughter bonding at the gala.

Mary-Kate and Ashley Olsen [6] were two of a kind hitting the red carpet.

Chrissy Teigen, Georgina Chapman, and Rita Ora borrowed each others' style.

Lena Dunham and Girls showrunner Jennifer Konner wore similar maroon gowns to the event.
