The YouTuber, who has over 4million Twitter followers and 16million subscribers, filmed a video and wrote a text post explaining why she wouldn't be filming any videos for a while after her taxi crashed on the way back from the airport.
She also shared 4 photos of her bruises on Twitter, urging people to wear their seatbelt and a reminder of safety in the car, before later explaining the true extent of what happened in a YouTube video.
We're wishing Jenna and Julien a speedy recovery, and hope this acts as a reminder to everyone about how important your safety is when you're in the car.
