Ashton Kutcher and his teenage stepdaughter SCOUT WILLIS have shown off their musical talents in a new online video.
The actor, who is married to the 19 year old's mum Demi Moore, is seen strumming a guitar in the clip while Scout sings a ballad, entitled My Sober.
Kutcher describes it as a "little song about a loved one" they wrote together, before adding: "I'm an awful guitar player!"
As well as playing the instrument, the actor also adds his vocals to the track, which has become an online hit since it surfaced earlier this week (begs24Jan11).
