Betty White recently celebrated her 93rd birthday and it didn't go unnoticed by her "Hot in Cleveland" sitcom family. They surprised Betty with a huge flash mob.

Betty is being driven, in a golf cart, to the set of her sitcom when the driver asks about her birthday. He tells her he thinks there is going to be a little celebration for her. When they round the corner there is a single hula dancer then comes a small group of dancers.They drive a few feet and more dancers come bouncing out, then a few more feet and more dancers. Finally comes her co-stars, Wendie Malick, Jane Leeves and Valerie Bertinelli along with producer Gary Marshall,  carrying a huge Happy Birthday sign.

You can tell that Betty is surprised and loved every minute of the attention. But she did jokingly mention at the end of the video that 'At 93, you shouldn't be doing this'.  Here's to many more birthdays Betty!
