Looks like the ad world isn't the only one focusing on fatherhood. Kanye West recently debuted his latest video for the track "Only One," a suprisingly emotional and simple film featuring Mr.West walking and cuddling quietly with his daughter North. Mr. West wrote the song from the point of view of his late mother, and Paul McCartney accompanies on piano.

Directed by Spike Jonze, it's quite a departure from Mr. West's more over-the-top clips, such as the one for "Power," which he likened to a "painting," and for "Bound 2," which featured him and Kim Kardashian doing the deed on a motorcyle.
