Hugh Hefner's ex-girlfriend Holly Madison has assured fans she is fine after she was involved in fender bender on Wednesday (05Feb14).

The former Playboy playmate shared a photo of what appeared to be blood splattered on the side of her face and in her hair on her Twitter.com blog, but she revealed the mess was actually made by a smoothie, which had exploded all over her upon impact.

Alongside the snap, she wrote, "My car got rear ended pretty hard. Luckily, this gruesome look is just the smoothie I had in my cup holder."

Madison, who did not offer up any information about other injuries she may have suffered, later thanked followers for their words of concern, adding, "Thank you for all the well wishes re: car accident! Yes I am ok".
