Kimberly Bell, the one time mistress of Barry Bonds from 1993-2003, is spilling the beans on all of Barry’s secrets while posing nude for Playboy magazine.

The Playboy article, accompanied by a nude pictorial of Kimberly Bell, is scheduled to hit newsstands Oct. 1. Bell, 37, said the article would cover details of her relationship with Bonds that she told a grand jury investigating the perjury allegations in 2005.

“The opportunity was there, and I took it,” she told The Associated Press in a phone interview Monday. The photo shoot “was one of the most liberating experiences of my life.”

She states that Barry started roids over envy of Mark McGwire breaking and setting the single season home run mark of 70 back in 1998. Barry, once on the juice, broke and set the record at 73.

She said posing of the men’s magazine ‘liberated’ her. She also got in this snide remark in relation to Barry.

“If I had more self-esteem when I was younger,” she said, “I wouldn’t have been caught up with such a rotten man.”

Ouch! But come on….you were with him for ten years before deciding this? Critics of Bell claim she turned on Bonds when he chose a different woman to marry.
