Maybe celebrities should just stop stepping out of cars, like, ever. While showing up for a radio appearance in London, Miley Cyrus accidentally showed off her underpants! Not that we think Miley probably cares all that much, as she's never exactly been shy in the past.

In this case, it looks like a total accident! Since her legs are together, the skirt probably just hiked up on the seat of the car. It happens to the best of us!

After the little accidental exposure, Miley, without missing a beat (maybe she didn't notice?) enthusiastically greeted fans outside BBC Radio 1.

Stray observations: her hair looks awesome, those sunglasses are great with her face shape, and the super-casual black t-shirt is a good vibe for her.

See the pic below! What do you think? Could've been worse?
