The new face of L'Oréal, Gwen Stefani, has revealed her new commercial for its Infallible le Rouge Lipstick. 

The thirty-second advertisement is full of fast cuts, shots of Stefani's signature red lip colour and scenes of the No Doubt star looking fantastic. 

No Doubt are currently back in the studio and have spent hours this morning (January 21) posting pictures of themselves working and recording through the band's official Twitter account.
