Simon Cowell's Golden Buzzer act on America's Got Talent sadly pulled out of the show due to her health taking a turn for the worse.
Nightbirde, whose real name is Jane Marczewski appeared on the show last night via video link.
Simon was clearly moved by talking to her, although he had privately phoned her previously.
Nightbirde said she felt she had let people down. Simon wanted her to know that she hadn't let anyone down by dropping out of the competition.
'Even though you haven't competed, you have already won,' Simon said. 'Your clip had such an impact on so many people.'
He said that the most important thing was her health and recovery. 'On behalf of all of us, we are sending you our love and our prayers and we can't wait to see you again soon.'
Nightbirde said the entire experience had restored her faith in humanity to see people come together.
'We all hurt, we all suffer, and we all have the potential to overcome,' she said.
'This is the most beautiful thing that has happened to me in my whole entire life,' Nightbirde added.
Sending Nightbirde all our love and prayers.
