Regular readers will know just how strongly I feel about the need to have models on the covers of magazines as opposed to celebrities. Gwen Stefani is an exception to the rule.

Aside from the fact that she's uber talented, she's one of the few celebrities, along with Sarah Jessica Parker and Lady Gaga, whose careers have been so extrinsically linked to fashion that having her on the cover of a September issue makes sense. After all, she is a designer in her own right too.

Today her Terry Richardson-shot US Harper's Bazaar cover dropped and it is everything we could have hoped for. The head piece she rocks on the cover works brilliantly and in the accompanying shoot Stefani sports that beautiful pink Jil Sander dress from Raf Simons' last collection at the house, along with that multi-tiered Alexander McQueen dress too.
