Patrick Schwarzenegger spent his Friday shopping for a Halloween costume in West Hollywood on Friday.
Unaccompanied by his model girlfriend, the 23-year-old actor brought along a male friend instead.
The trip was successful as the two were spotted walking out of a costume shop with goodies in hand.
The USC grad stayed true to his boyish nature and grabbed a Bowser costume.
He later posted a photo in the costume, captioning it with a simple, 'Yup.'
The young rising star looked cool and casual, wearing a white long sleeve tee, light gray jeans, and cream-coloured high top sneakers.
He topped the look off with an LA Rams cap.
