AceShowbiz - Billie Eilish sent her fans into a frenzy with her new video on social media. The "Bad Guy" hitmaker, who unveiled a music video of her new single "Lost Cause" earlier this week, took to her TikTok account to dance to the slow R&B track alongside with models who were featured in the visuals.

Donning light blue silk pajamas with plunging neckline, the 19-singer showed a huge amount of cleavage. Billie and the girls opened the clip, which she uploaded on Thursday, June 3, moving their bodies seductively to the music.

When she was about to get up and dance, Billie accidentally experienced a nip slip. The Grammy winner wittily covered her chest with a sticker. Poking fun at the accident, she added a voiceover saying, "Titties falling out."

She also covered her bottom with a huge sticker across the video during part of the choreo that saw her and the other girls twerking their derriere. "not showing u this," said the voiceover.

In response to the sultry clip, Internet users understandably went crazy. "Who knew Billie had all that up under there! Go head Billie!" one person wrote in an Instagram comment. "I just love to see anybody enjoying life and laughing at the imperfect parts of it. do ur thang Billie and company," another comment read. "I've never seen this much of Billie's skin," a surprised fan added.

Meanwhile, some others appeared to clown Billie, prompting her fans to defend the young singer. "No Billie slander is allowed," one loyal fan said. "She's living her life and having fun. Leave her alone," one other fan urged, while someone else noted, "I love how comfortable she has become."

"Lost Cause" is the fourth song that is released ahead of her sophomore album "Happier Than Ever", which is set to be dropped on July 30. Other songs that will be included in the highly-anticipated album are "My Future," "Therefore I Am" and "Your Power", all of which landed in the Top 10 of the Billboard Hot 100.
