Gwen Stefani was all smiles yesterday, arriving at a Parisian TV studio for an appearance on France's C à Vous. Gwen and the boys of No Doubt are currently overseas promoting their latest album, Push and Shove. It's been a busy few days for the group, who kicked off this year's iHeartRadio Music Festival on Friday night in Las Vegas. They were the first of many bands to take the stage and performed a one-hour block of songs ranging from their classic singles like "Don't Speak" to their most recent hit, "Settle Down." So far the band has released two songs from the album, and today they're looking forward to releasing the official music video for "Push and Shove."
