Billie Eilish Touts 'Indestructible' Chest With Bouncy Slaps

Billie Eilish gave a visual demonstration of the power her chest delivers late Monday night when she decided to concoct a fun way to get her dog's attention. Without saying a word, the "bad guy" singer turns the camera on herself and gives one of her breasts a big whack! The noise reverberated through her house and gave her doggo quite a shock, while her assets revealed a hefty jiggle while seemingly avoiding any pain.

It wasn't an isolated event, as Eilish continued to give herself a thwack while letting out a satisfied laugh.

Apparently, fans were sending Billie Eilish messages about the punishment on her boobs, so the singer answered every one in an honest video message:

"When you've got yitties like this ... nothing hurts," Eilish explained while shooting a coy smile and continuing to show off her bouncy behavior.

The singer then labeled her reported 34D's as "indestructible."

The appreciation for her body comes during a big year for Billie Eilish, after she debuted the powerful short film earlier this year, "Not My Responsibility."

Back in May, Eilish dropped a YouTube video that dealt with body image, shaming and confidence as the singer has been faced with many of those issues during her meteoric rise to fame.

"Some people hate what I wear. Some people praise it. Some people use it to shame others. Some people use it to shame me. But I feel you watching, always, and nothing I do goes unseen," Eilish says in the video while removing layers of clothing.

Eilish continues, "So, whether I feel your stares, your disapproval, or your sigh of relief—if I lived by them, I’d never be able to move. Would you like me to be smaller? Weaker? Softer? Taller? Would you like me to be quiet? Do my shoulders provoke you? Does my chest? Am I my stomach, my hips?"

Billie Eilish is making it clear her body is her own business ... including the bouncy slaps!
