Happy 98th birthday Betty White! Watch as she receives a surprise birthday flash mob dance

The world's golden girl Betty White is celebrating a long and bountiful life, turning 98-years-old today!

While the birthday girl plans to mark her special day with a "small group of pals" and a lot of "good humour", we're throwing it back to five years ago when Betty received one awesome surprise in honour of turning 93 at the time.

Because what do you give a gal who already has everything? A flash mob of hula dancers, of course.

Every day on the set of Hot in Cleveland, Betty was greeted by her assistant with a hula ... but on January 17, 2015, the hula dance was an extra special one.

Sporting grass skirts and leis, the mob danced around Betty’s golf cart as she was driven around the soundstage by Canadian actor Dave Foley, who played Bob on the show.
