Move over Keenan...YouTube's next big sensation is set to be the Kutcher-Willis band.

In "My Sober," Ashton Kutcher and Scout Willis pay tribute to many folks' beverage of choice: coffee!

Demi Moore's hubby and daughter serenade the caffeinated treat with quippy lines like, "You're my sober when I'm wasted/ You're my courage when I've got a doubt/ You're my happy when I'm grumpy/You're my smile when I'm stuck with a pout" and "You're my weapon 'gainst the sandman/ Feel so warm in my hand."

EMBARRASSING CELEBRITY PARENTS

This isn't the first time that the Moore-Kutcher household has been an internet sensation. Demi Moore encouraged a bikini-clad following, after posting photos of herself, wearing a bikini.

Ashton and Scout end their song with a high-five!

In a matter of days, the clip has received almost 300,000 hits. Ashton apologised for being 'an awful guitar player' but happily strummed along as Scout showcased her sweet singing voice. Just going to show, that you can be a internet sensation with very little talents. Many viewers comments were impressed with Scout's vocal ability. Not surprising given her parents success, and her siblings up and coming star-quality.

While her sister Rumer is embarking on a professional modelling career after becoming the new face of Badgley Mischka, Scout is in her second year at Brown University at Providence, Rhode Island. Other famous Brown alumni are Harry Potter star Emma Watson, Allegra Versace, Jack Nicholson's daughter Lorraine, and George Harrison's son Dhani.

Ashton Kutcher's most recent movie 'No Stings Attached' stars mum-to-be and Oscar favourite, Natalie Portman.
