Much as we adore Britney Jean Spears and the absolute corkers she has gifted the music scene over the past 18 years, it's fair to say she wasn't blessed with a voice quite as powerful as Christina Aguilera, Whitney Houston or Mariah Carey.

And that's fine – good ol' Brit brings her own thing to the stage, and we're always here for it.

So when she uploaded herself performing a rendition of Elvis Presley's Can't Help Falling In Love in honour of her 36th birthday, we couldn't hit play fast enough.

The 36-year-old clearly gave it her all, and props for that as they say, but if we had to choose, we'd probably opt for a quick blast of Toxic next time.

While some Instagram users compared her voice to a chipmunk's, hundreds others heaped praise upon the performance, with one writing: "Truly blessed with your beautiful voice."

We'll let you be the judge of that one…
