And although she knows what the lyrics mean, she "wasn't thinking about them" when she was singing them.
"First I want to thank Ellen for just being incredible she will always be blessed because of her HUGE Heart!,' Missy said on Instagram following the show".
"It was a shock, I never expected this", said Halsey about going viral and getting a response from Missy for the original video.

Missy Elliott met her long lost sister on Ellen - her funky white sister, that is.
Missy Elliot dueted "Work It" with a fan who has been slaying her song in karaoke for 15 years.

Sitting down for a chat, an overwhelmed Mary admitted: 'I can hardly just sit here, you've blown me away.
In the end, not only did Missy give Mary a signed T-shirt, but Ellen also gave her a jacket that had the words "Missy's Funky White Sister" emblazoned on the back. I thought it was just the most incredible thing.
