Billie Eilish

Billie Eilish briefly lost her cool at a gig in Texas over the weekend after realizing a fan had nabbed her ring.

The Bad Guy singer was performing at the Austin City Limits Festival when she realized one of her jewelry pieces was missing after walking though the crowd, shaking hands.

"Somebody stole my f**king ring!" she scowled as she returned to the stage, but quickly changed her tone as the audience angrily began demanding the thief give it back.

"I guess that's my fault," she added. "Keep that s**t. Take care of that s**t. The ring is gone for good. It's OK, don't worry about it. Whoever has that s**t though take care of it, OK."
