In an episode of the “SmartLess” podcast that was released this week, the Oscar nominated star of “The Fighter” and “Enchanted” said she was leaving a restaurant in Santa Monica with her family when she noticed a disturbance nearby.

“These people were screaming and a guy was walking and they were yelling, ‘He’s dying!’” she told hosts Will Arnett, Sean Hayes and Jason Batemen.

While Adams’ husband, Darren Le Gallo, stayed with their daughter, Adams said she and her father jumped in to assist.

“He’d been stabbed in the neck,” she said. “So he was bleeding and his friends were freaking out.”

They grabbed beach towels to help stop the bleeding, with her father applying pressure to the wound while Adams worked to keep the victim calm and focused on breathing.

As she spoke to the injured man, Adams said she drew upon her brief experience playing registered nurse Alice Doherty on “Dr. Vegas.”

The series, which starred Rob Lowe as Dr. Billy Grant, aired on CBS for just five episodes in 2004.

She recalled repeating the advice, “The more you struggle, the faster you’re going to bleed. Just lay down.”

Adams also revealed that she unexpectedly crossed paths with the victim about a year after the incident.

“A guy walks up to me in a restaurant,” she said. “He’s like, ‘I heard a story that you and your dad were on the scene of a guy getting stabbed.’ And I was like, ‘Yeah, that’s so funny you heard that story.’”

“I was like, ‘Oh my God, it’s you,’” Adams said. “He was all teary and he had his son with him. It was so crazy.”

Adams, who was promoting her new Apple TV series “Cape Fear,” joked that she always wanted to be a doctor.
