Watch: It’s hard to not smile during dad’s duet with 3-year-old daughter

DALLAS, Texas – When it comes to dads and daughters, little girls can make the toughest guys seem like marshmallows.

That’s exactly what happened with a dad named Billy and his 3-year-old daughter, Blakely.

Like a lot of little girls, Blakely is a big fan of ‘Frozen.’

While Billy may not know all the words to ‘Let it Go,’ he is full of encouragement to help Blakely steal the spotlight.
