In last night's Celebrity SAS: Who Dares Wins Katie Price became the first star to quit the show and has blamed her boobs for becoming inflamed.
The 41-year-old mum of five was trying to lift a sandbag over her head, but just wasn't up to the task.
Now, the former glamour model has said she wasn't medically able to do the gruelling challenge - insisting that it wasn't just because she wasn't fit enough.
Katie said: "I pulled something in training. My breast reduction became inflamed. It was out of my control. I was gutted. I had to leave because of the pain I was in.
"I'll never take my creature comforts for granted again. I left with new life goals. I left the old Katie up there. She's not coming back."
After giving in, she went into the medical room where she said: "I'm so p***ed off, I didn't have the strength to keep holding my arms straight. It's not an excuse it's just me, how it feels for me.
"I will always f***ing beat myself up. I'm so pissed off with myself."
The show has become well known for not hiding anything or treating the contestants differently because of their celeb status.
The 12 well-known faces will embark on the toughest test of their lives facing a gruelling course in the challenging terrain of the Scotland's rugged West Coast.
