When Kathy Bunker took to the dance floor for the customary mother-son dance at her son Blake's wedding last April, guests likely anticipated something lovely.
Kathy is, after all, the owner and artistic director of Bunker Dance Center in Las Vegas, Nevada. She knows how to dance.
About one minute into their slow waltz to the Nat King Cole ballad "Unforgettable," the pair stopped, blaming technical problems.
Moments later, the mother and son duo proceeded to tear up the dance floor with a party-rocking routine making for an "unforgettable" night, indeed.
"We decided to do this only a few weeks before the wedding," Kathy tells Trending Now. "We thought that we should do something besides the typical dance."
The duo choreographed their routine on a Sunday afternoon, letting no one but the bride in on the dance surprise.
