Britney Spears Is A 'Son Of A Bitch' In These Bikini Teasers

Nathaniel Rateliff & The Night Sweats soundtrack Brit's mysterious new visuals.

Turns out, Britney Spears is a Nathaniel Rateliff fan! So much so that she decided to writhe in a bikini to his song "S.O.B."

Miss Spears, who's recording her ninth album and maybe an EP, posted three black-and-white teasers to Instagram on Monday night. But are the visuals for a new project? A new music video for a brand-new song, perhaps? A new perfume ad? Just for fun?
