Gail Kim recently appeared as a guest on Wrestling with Rosenberg and she made some fascinating comments about the events that resulted in her quitting WWE the second time. Her final appearance on WWE TV was on the August 1, 2011 episode of Monday Night Raw when she infamously eliminated herself from a Divas Battle Royal.
In the interview, Gail said she decided to quit WWE the day they introduced the angle to her that she would be Daniel Bryan's secret girlfriend in the program with The Bella Twins. She said that when she went in that day with her boyfriend/now husband Robert Irvine that she decided to go with the flow.
Gail said the USA Network apparently didn't like the Bella Twins fighting over Bryan so her inclusion was the new direction. According to Gail, she was the third choice behind Sara Del Rey and Awesome Kong and they went with her because she was already on the roster. Once the angle concluded, she was frustrated about being phased out again. She said John Laurinaitis asked her if she wanted to train Divas at the company's developmental territory and she didn't want to do it.
Her infamous exit was due to frustration, as we noted back when it happened. You can watch the entire interview at this link or embedded in the video below:
