"Things happen in life, and don't let your past get you down. You can always overcome -- you can overcome anything you want to and be a better person. Don't let people tell you that you can't."
Kayden Cash Sierra -- whose middle name refers to Sierra's affinity for Johnny Cash -- weighed 6 lbs., 12 ounces at birth. Sierra declined to reveal the baby's father and instead told RadarOnline it is an "ex-boyfriend."
"But a very good friend -- a best friend," she told RadarOnline.
It was a bumpy road for Sierra after she finished tenth during American Idol's Spring 2005 fourth season.
She was arrested in April 2007 and charged with aggravated battery with a deadly weapon, possession of cocaine and introduction of contraband into a detention facility.
In January 2008, Hillsborough County Circuit Court Judge Daniel Perry ordered Sierra stay at least 100 yards from microphones and cameras because he didn't want her to use treatment on Celebrity Rehab with Dr. Drew as a way to aid her celebrity status and thus "glamorize" being a drug addict.
Sierra said she has been sober for two years and is currently in the studio working on a new album.
"On December 1, I got two years," she told RadarOnline. "Don't get me wrong, I'm not healed or anything. I still suffer from alcoholism."
