Martha Stewart in touch with prison buddies

Lifestyle queen Martha Stewart has no regrets about her 2004 stint in prison - because she made some "interesting" friends in jail.

The media mogul was jailed for five months in October 2004 after being convicted of lying to federal agents investigating insider trading.

During her time at Alderson Federal Prison Camp in West Virginia, Stewart admits she formed a group of pals who she is still in touch with, more than three years after her release in March 2005.

She tells Fortune magazine: "Some of the women who became my friends while I was incarcerated have visited with me. There are some very interesting women there of great value to society, and I keep in contact with them. We have some broken systems in this country - one is the prison system."
