Britney Spears Back and Looking As Hot Ever in New Vid Clips

Britney Spears made a bunch of black and white videos that look like the most awesome #flashbackfriday ... on a Tuesday.

Although it's unclear what she's teasing in the videos, TMZ has learned that Britney is feeling great, getting ready for her revamp Vegas show and just having a good time with social media.

The clips are amazing, though possibly too hot to watch for too long -- especially at work.

It's like early 2000s Pepsi all over again. The commercials, not the soda.
