Sitting down with Hoda Kotb and NBC London correspondent Keir Simmons, Kellie was eager to hear Keir's best southern accent!
After some back and forth, he gave his best "Hey y'all! How y'all doing?", leaving everyone laughing!
Kellie tried to give him some tips, and he said "This is so bad. I will never be able to travel!"
However, Kellie's London accent was pretty spot on!
After wowing the show with her notable rendition of Simmons' accent, Kellie had everyone laughing with her Long Island accent.
