Samantha Ronson took to Twitter to post a photo of herself following a bike accident on Saturday.
The DJ - pictured in October 2009 with brother Mark - was left with bruises on her face and a split lip. She posted the picture on Monday as a warning, tweeting: "Wear a helmet kids!!!"
The 33-year-old joked: "You should see what I looked like on Saturday. Just a little uglier than usual. Other than that, Vicodin is handling the rest."
