Betty Ford -- the free spirited, former First Lady who bravely went public with her own drug and alcohol addictions to help others -- has died at the age of 93, RadarOnline.com has learned.

Mrs. Ford -- who was married to late President Gerald Ford for 58 years -- passed away Friday at the Eisenhower Medical Center in Rancho Mirage, California with her family at her side.  No other details of her death are being released at this time.

"Mother's love, candor, devotion, and laughter enriched our lives and the lives of the millions she touched throughout this great nation," her family said in a statement released late Friday. "To be in her presence was to know the warmth of a truly great lady."

Lindsay Lohan's appeal of Judge Stephanie Sautner's ruling to send the embattled actress to jail for 120 days for violating terms of her probation, could take at least 2-3 months to be heard.

Meanwhile, the troubled Mean Girls star will remain free on bail until the appeal is formally heard.

However, sources close to the DA’s office, tell RadarOnline that: "Lindsay's appeal will most likely be denied. The only thing this appeal is doing is buying Lindsay time to stay out of jail.

Lindsay Lohan is heard arguing, screaming and even grappling with Betty Ford worker Dawn Holland during the dramatic 911 call obtained by RadarOnline.com.

The incident occurred on December 12, 2010 when Holland accused an "out of control" Lohan of throwing a phone at her after being caught allegedly drinking and violating curfew - which lead the Palm Desert Police Department to investigate the 24-year-old for breaching her probation.

"I'm sorry...I'm really uncomfortable with the woman that's in our house. I've never seen her before and she's freaking us out," Lohan is heard telling the 911 operator.

Holland is then heard on the phone telling the officer she wants to speak with him but only if Lohan gets off the phone.

When Dina Lohan broke the news to her daughter Lindsay that she would not be charged with any wrongdoing in connection with an altercation at the Betty Ford Center, the troubled actress told her mom: "Great, Awesome. Thanks Mommy. Goodnight!", RadarOnline.com has exclusively learned.
