Rihanna's Bruised Face Caused By Nasty e-Scooter Accident

Rihanna appeared bruised and battered as she made a quick pit stop in L.A. -- turns out she's the latest victim of the electric scooter.

RiRi rolled up to Giorgio Baldi in Santa Monica Friday night, where she was trying to lay low in her Escalade while some staffers brought out food and drinks to her curbside. At one point, she removed her sunglasses ... and paps captured her looking the worse for wear -- a black eye and some swelling in her face.

Several media outlets posted the photos and suggested she'd been in some sort of physical altercation ... remembering the Chris Brown beating back in 2009. Not the case -- her rep tells us Rihanna was on an e-scooter a few days ago and ate it after the scooter flipped over, smacking her in the face and forehead.

We're told it looks worse than it is and she's healing.
