Gwen Stefani Releases Push and Shove in Paris | Pictures

Gwen Stefani and youngest son Zuma Rossdale arrived in London today via train after spending last night in Paris. No Doubt's currently in Europe promoting the release of their new album, Push and Shove, out today. Yesterday, No Doubt made a quick stopover in France to perform the album's title track live on C à Vous.

Today is all about a media blitz for Gwen and her bandmates, Tony Kanal, Adrian Young, and Tom Dumont. Gwen pretaped an interview with Ellen DeGeneres that airs on The Ellen DeGeneres Show. She also called in this morning to chat with Carson Daly about family, touring, and the album's second video, "Push and Shove," which also came out today. The five-minute video shows Gwen and the guys partying on planes, in bars, and on the street, and coincidentally, Gwen's wearing the same black and white trench that she has on today.
