"Baby Phat" is the only official single from De La Soul's sixth studio album, AOI: Bionix, released in late 2001. The song was produced by Dave West and featured vocals from Devin the Dude and Yummy Bingham. This single was the introduction for Yummy Bingham, who simultaneously established herself as De La Soul's appointed vocalist and as a member of the short lived R&B group Tha Rayne.

The song is an ode to "plus size" women, as Devin sings "Don't get stuck on the things they say, now you know it's a nasty world / Tryin' to get with ya anyway cause I know you're a nasty girl / We ain't never gon' discriminate so let me compliment your size"
