The 45-year-old, who announced her split from Franchitti in January after 11 years of marriage, was there by his side after he was injured in a crash at the Houston Grand Prix in Texas, US, Oct 6.
The couple has since then sparked rumours of their reconciliation, reports contactmusic.com.
"Something good has already come out of this terrible accident. It's brought Dario and Ashley closer together again and on the path to patching things up," a source told National Enquirer.
"They still love each other very much, and Ashley was very distraught when she heard about Dario's crash. She had tears in her eyes and immediately began praying to God he would pull through," the source added.
Franchitti, 40, sustained a broken ankle, two spinal fractures and a concussion in the crash.
Post the accident, Judd also thanked her fans for their support via microblogging website Twitter.
