Model Lauren Scruggs -- Celebrates 24th Birthday with New Prosthetic Arm

Lauren Scruggs -- the model who suffered gruesome injuries in a plane propeller accident last year -- celebrated her 24th birthday and showed off her new prosthetic arm in Texas on Wednesday.

Last December, Scruggs lost her left hand and left eye after accidentally walking into an airplane propeller. She has been undergoing extensive rehab and a few months ago settled with the airplane insurance company for an undisclosed amount.
