While we're missing Paris and Nicky Hilton here in Los Angeles, it looks like the stunning siblings are having a blast in New York City!

On Saturday she tweeted, "With @NickyHilton at Yankees Stadium sitting front row watching @Avicii & @Madonna perform! #Epic! #YES! ... We love @Madonna so much that we are here in rain ponchos! Lol! Such an #Icon!"

The next day the heiress posted this photo of the ladies at the Diane von Furstenberg dinner, adding, "Having the best time at #NYFashionWeek!" Paris has been spotted at shows for Marlon Gobel and Charlotte Ronson, but sadly it looks like she wasn't able to make it to one of the events on Sunday. "#NYC traffic is crazy," P tweeted. "Missed one of my favorite fashion shows." Boo!
