Jenelle Evans says she sustained gruesome injuries during a domestic violence incident just before her arrest on Tuesday -- and Breaking Celebrity News has exclusive photos of the bloodied reality star.

“Jenelle has been saying that she was hit in the head by Courtland and it made her ear bleed,” said a friend said of the Teen Mom and her estranged husband, Courtland Rogers. “That’s why the cops were called.”

In one photo, Jenelle’s left ear is bloody; in another, her hand is covered with blood. And the 21-year-old apparently has reason for sharing the shocking pictures.

“She gave these photos to her friends, and they said she wants people to see what happened to her,” the source told Breaking Celebrity News.

“Jenelle is going to fight these charges because she wasn’t responsible -- Courtland was.”
