Singer Louisa Johnson's Britney Spears Halloween costume requires a double-take

Gibson Johns,

It's Britney, bitch! Wait, actually, it isn't. 

British singer Louisa Johnson sent pop music fans into a tizzy on Thursday when she posted photos of her Britney Spears Halloween costume on social media, with many pointing out the uncanny resemblance that Johnson has to Spears in the photos.

Channeling Spears' iconic MTV Video Music Awards performance of "I'm A Slave 4 U" from 2001 -- the one with the snake -- the former winner of the UK's "The X Factor" looks so much like the pop music icon that the photos require more than just one double-take.

See Louisa Johnson's Britney Spears costume -- and Britney's original look -- below:

Johnson wore the outfit to the Kiss Haunted House Party in London, where a ton of other stars wore costumes, but the "Unpredictable" hitmaker more than stole the show in her embellished hot pants, green bra top and perfectly tousled hair. Oh, and did we mention her incredible, Britney-esque abs?

The only thing that was missing was the snake! Johnson opted not to risk her life by draping a python around her neck like Britney did 16 years ago.

Johnson isn't the first star to dress up as another celebrity, of course. Remember last year when Kylie Jenner channeled Britney Spears' fellow pop diva Christina Aguilera?
