Ashton Kutcher and his stepdaughter Scout Willis collaborated to write "a little song about a loved one" that they perform together in this YouTube clip.
Scout appears with a big puffy hat and sings vocals while a sports jersey-wearing Ashton plays guitar, although he states beforehand: "I'm an awful guitar player -- let that be known."
The two then cheerfully sing a tune called 'My Sober,' which includes such lyrics as: "You're my happy, when I'm grumpy, you're my smile when I'm stuck with a pout."
