Billie Eilish almost did a whoopsie in when Britney Spears danced to her songs

You learn a lot of interesting things on BILLIE EILISH's podcast, "me & dad radio".  For instance, the first time Billie saw an Instagram video of BRITNEY SPEARS dancing to one of her songs, she almost SOILED HERSELF (!!!????).

Billie's a huge Britney fan.  Especially "Baby One More Time".  She said, quote, "This is an incredible song.  Dude, this era of Britney was just, like, mind-blowing."

"I used to dance in the living room to this on my tiny little horrible speaker."
