Teen performs dance with grandma from safe distance during grocery drop

An 18-year-old is delighting millions on TikTok with an adorable performance guest starring his 76-year-old grandmother.

Lewis Leigh, a resident of the U.K., told "GMA" he taught his grandma, Phyllis Leigh, lovingly known as "Nan," a viral dance from the video sharing app while standing at a safe distance.

"Everyone just saying it's a wholesome video," Lewis said. "It's upsetting because my grandmother lives on her own so the highlight of her week is when my family and I visit."

Lewis has been maintaining space from his Nan amid the novel coronavirus crisis and was dropping off groceries to her before sharing the dance.

"I did not expect her to pick it up so quick," Lewis said. "I thought the exercise would be good for her."

The video has over 4 million views on TikTok.
