Last week we were introduced to Jack, a young fan of the Vancouver Canucks who got the crowd at Rogers Arena going with an enthusiastic and expertly rhythmic dance to LMFAO's 'Sexy and I Know It.'

We learned a little more about the pint-sized performer this weekend, thanks to an interview he and his family did with 'Today.'

Jack Millos, who was six at the time the video was shot, actually turns seven today. And the older fellow who was sitting behind him in the viral video, and enjoying Jack's dance thoroughly, is his dad Ron.

But Jack credits his dancing skills to his older sister Teegan, who he says taught him all of his moves. And apparently his dancing isn't only limited to hockey games, as 'Today' was given a home movie of younger Jack doing his thing to the Black Eyed Peas' hit 'Boom, Boom, Pow.'

However, it's 'Sexy and I Know It' that is Jack's favorite song. He wanted to dance to the LMFAO hit for his school's talent show, but he didn't because his mom wasn't sure how the school would feel about the racy lyrics.

Since then it's become clear how the internet -- and we suspect 'Today's' audience --  feels about Jack's dancing. Looks like his elementary school missed out. Jack's just gotta dance.
