Paul Wall Reveals admits going under the knife, and losing more than 100 pounds.

Wall's decided on surgery after reps for VH1's "Celebrity Fit Club" were contacting him about coming on the show. Paul says, "that was a h*ll of a wake-up call". See what he looks like now...

"[Being fat] isn't a secret. You can look in the mirror and try to hide it and cover it up, and it may work here or there, but there ain't no shirt or hat you can put on or haircut you can get to hide the fact that you're morbidly obese. That's what the doctor said: I was 'morbidly obese.' I decided not to do [the show] but it was still a wake-up call to have people calling you saying, 'Hey, you're really, really fat.'"

The rapper also reflected on getting gastric sleeve surgery and why losing so much weight was vital.

"I feel like I got my life back. When you're so big like that, it's embarrassing. I didn't want to go out and be seen. I felt uncomfortable because I'm not used to being that big. People would see me and say something about it, because it was no secret. I was morbidly obese, 120 pounds overweight. It was just embarrassing. I'd be on stage feeling like I was about to collapse. I'd get dizzy spells. I'd be on the airplane and have to ask for seatbelt extensions. Once you go up in the air, it's really hard to breathe.

"I was just thinking, 'What if I have a heart attack?' I want to be here for my kids. I don't want to have a heart attack. My son is four and my daughter is two and a half. The doctor told me that when you're 50 pounds overweight, it takes 15 years off your life. So it literally saved my life."
