Shay Mitchell (Emily) may not have been able to get festive for Halloween this year, but she still managed to jump on the Miley Cyrus costume bandwagon in her own way.

The Pretty Little Liars actress took to Instagram, posting a throwback pic of herself with her tongue sticking out of her mouth. Along with the pic, she wrote, "Since we won't be dressing up today due to shooting our LAST day of the season(!)... I will throw it back to a past Halloween... #doingtheMiley." Attagirl!

Shay's not the only celebrity who did the Miley this Halloween. Paris Hilton also dressed as the Bangerz singer for a party at the Playboy mansion, and even Hugh Hefner and his wife Crystal dressed up as Robin Thicke and Miley during the party. Perez Hilton also rocked the foam finger look during Heidi Klum's Halloween party in NYC last night. It looks like this year, everyone's "just being Miley!"
