Willow Smith Willow Smith has released her debut album Ardipithecus.

In a statement about the record to Fader Smith said: "Ardipithecus Ramidus is the scientific name of the first hominid bones found on earth. I wanted to name my musical compilation after it because, while I was making these songs I was in such a transitional state.”

“Digging deep in the soil of my heart and finding bits and pieces of my ancient self that tell stories, which end up being the lyrics to the songs. Ardipithecus is my first album in my entire career and it makes me feel so blessed to be able to share my evolution with the LightEaters as I continue excavating my inner worlds…”

The 15-year-old is credited as the sole songwriter on 14 of the tracks and as the producer on 10 of them. Earlier this week Smith teased that she might have something special planned for Friday, by posting an Instagram message which simply read: 'Dec. 11th.’

But the album contains some controversial lyrics, with the teenager making references to sex and drugs. On opening track ‘Organization & Classification’ Smith sings 'I call it crystal, man. You call it rock.'
