Mingling with their closest friends while celebrating the Halloween holiday, Aly and AJ Michalka treated fans to some party insider pics from the weekend festivities.
The "78violet" singers took to Twitter to share the fun-filled photos, as the ladies posed in one shot alongside fellow former Disney star Miley Cyrus - who was looking ever so ghoulish for the west coast costume party.
Her party always seems to draw out one of the stronger fields each year, and this time around was no different as the stars turned up in the droves for Kate Hudson's Halloween bash on Saturday night (October 29).
Held at the "Fool's Gold" actress' Pacific Palisades estate, costume-clad revelers such as a J Lo dressed Nicole Richie, a bumble bee beautiful Ali Larter and a 60s inspired Zooey Deschanel all shuffled inside for the A-list laden fete.
Turning up for the designer's debut runway show at Mercedes Benz Fashion Week, the ladies were gathered together at The Plaza Hotel in New York City for the Marchesa Spring 2012 Fashion Show on Tuesday evening (September 13).
