Thinking of Madonna‘s impromptu Instagram cover of “Toxic,” Britney Spears filmed her own little performance video this weekend. The pop star shared a clip of herself singing a rendition of “Can’t Help Falling in Love,” the ballad originally recorded by Elvis Presley, without any accompaniment. She posted the a capella video on social media Saturday (Dec. 2), which happened to be her birthday.

“I was really inspired yesterday by @madonna’s post. She’s right… silence = death! These words really stuck with me, because they are so true,” Spears began in her Instagram caption.

She wrote, “I’ve always wanted to do a performance like this… singing in a pretty little black dress, with a simple 360, one take shot! I figured since it was my birthday, why not go for it?! So boom, when the clock struck 12:00, I did it!!!”

Spears has clearly been having fun with instavids lately: on Friday, she gave fans a peek at her Christmas decorations and how she’s celebrating the holiday season with boyfriend Sam Asghari.
