Billie appeared makeup-free for the occasion, donning a black and white baseball cap while keeping her hood up and the drawstring ties.

Her black locks framed her face with her choppy bangs and she was holding on to a teal water bottle.

With a backpack slung over her shoulders, Billie wore a pair of black three-quarter length leggings under her white, red, and black baseball shorts.

She opted for a pair of red and white high-top sneakers that perfectly matched her casual ensemble.

The masked intruder was reportedly dressed all in black and was seen lurking in the backyard.

The property’s house sitter, who was not there during the burglary, received a notification showing the man, which led to the sitter calling the police.

The suspect was arrested a block from the home during a search of the area.

Authorities assumed nothing was stolen from the house, which belongs to the singer’s entire family.
