When Tracy Morgan needed a kidney to undergo life-saving surgery in December, he turned to his ex-girlfriend for help, but according to the star's brother and mother, he kept his operation a secret from his family.

In an exclusive interview with RadarOnline.com, James Morgan has spoken out about his sibling's controversial procedure, and the shocking way he found out about the news.

"I've been with him at his home, and he didn't let me know anything," he said, when asked if Tracy ever spoke to him about his need for a new kidney.
