Happy 93rd Birthday Betty White! Hollywood icon surprised by hula flash mob

(WITI) -- As of Saturday, January 17th, it's officially Betty White's 93rd birthday -- and she received one special surprise!

Every day on the Hot in Cleveland set, Betty is greeted by her assistant with a hula. So in honor of her special day, she was greeted not just by her assistant in a hula -- but an entire hula flash mob!

In the video, Betty seems surprised by the dancers jumping out dancing, complete with hula skirts and lei's.

By the end of the ride, 93-year-old Betty gets emotional as a sign is brought out saying "Happy Birthday Betty!"

In true Betty White form, she reacts by saying, "At 93, you shouldn't be doing this!"

The video is pretty cute -- check it out here:
