The Tennessean reported that Bon Jovi was filming a music video on the bridge, which remained open to the public during the shoot.
Video that was posted to YouTube but later removed showed the assistant talking to the woman. The Grammy-winning front man slowly approached, waved to the woman and joined in the conversation.
EDITOR'S NOTE — In the U.S., the national suicide and crisis lifeline is available by calling or texting 988. There is also an online chat at 988lifeline.org.
Eventually the woman turned around to face the two, and they helped her over the railing to safety. Bon Jovi talked to the woman and hugged her.
A representative for the singer said Bon Jovi would not be commenting on the incident.
