Ariana Grande rocked cat ears again last night on Saturday Night Live, where she was Christ Pratt's music guest.

It's unclear if this was an early Halloween costume debut, the pop star trying out a new signature look, or if it has any link to her Nickelodeon character Cat Valentine.

It seems as if it may be a new accessory added to her every day appearance. She also donned the cat ears at the iHeart Music Awards where she won the "iHeart Radio Young Influencer Award."

She also has pictures on her Instagram with her signature high pony tail and now-signature cat ears walking the streets of Tokyo and singing with Niki Manaj.

Here's a clip of Grande singing "Break Free" with her cat ears last night:
