Hollywood's most stylish stars from the 2015 Met Gala kept the party going into the wee hours and hit up some sweet soirees all over town.
Robert Pattinson and Kate Hudson were spotted catching up at Michael Kors' late night bash at the Mark Hotel. Everyone from Katie Holmes, Keri Russell, Mary-Kate and Ashley Olsen to a well-behaved Solange Knowles were also photographed letting loose inside.
Apparently on-again couple Katy Perry and John Mayer were spotted arriving to and leaving the same soiree within minutes of each other last night ... and, according to Us Magazine, were seen sharing "many passionate kisses and holding hands" once inside.
Meanwhile, Kendall and Kylie Jenner were snapped leaving Rihanna's post-Met party, both showing off their toned tummies in crop tops.
Kendall changed out her side-boob-baring Calvin Klein gown and into a snakeskin top and orange leather skirt. Her younger sis skipped the red carpet and kept it casual in jean shorts and a black Moschino mesh bralet.
After Rihanna literally took over the red carpet with her fur-trimmed, yellow Guo Pei robe, she switched it up for her bash and went with a completely sheer black top and black pants.
Whether she's covering the entire Met stairs or hitting the town, this pop star certainly knows how to make a statement!
Other celebrity sightings included Madonna, Justin Bieber, Jennifer Lawrence, Diddy, Chrissy Teigen, John Legend and many, many more. Check out the gallery above to see all the crazy after-party pics!
