Tributes to Whitney Houston have been in no short supply ever since the pop diva died a week ago. But one of the best comes courtesy of 90-year-old dancing grandma Jeanne Harr.

"'I'm doing this in honor of the late Whitney Houston. It's very hard to think of her being gone," Harr says at the beginning of the video. Then she launches into an energetic dance to Houston's 'I Wanna Dance With Somebody (Who Loves Me)' that totally defies her ripe age.

What makes the video even more impressive is that Harr is legally blind and suffers from moderate hearing loss. Still, she shows no signs of slowing down as she busts a move to Houston's '80s gem.

This isn't Harr's first attempt at cutting a rug, by the way. There are more than a dozen videos of the Utah granny on YouTube, dancing to everything from LMFAO to the Black Keys. (Watch her in action below.) Work it, granny! Whitney would be proud.
