Things started off with Gwen (looking cute in her trademark cutoff wife beater) and Shalom hitting the gym.
And somehow after a grueling workout she still managed to look AMAZING.
Then it was off to the Roseland Ballroom -- where No Doubt was headlining.
Backstage Shalom lived out the ultimate fantasy -- playing dress up in Gwen's clothes!
Gwen even showed off some of her cute Disney inspired stage outfits.
And also her messy side -- admitting this what her room looks like.
Unfortunately, all the fun ended when it was time for Gwen's soundcheck.
But before she left, Shalom got a chance to meet the rest of the band...
...and a totally once-in-a-lifetime opportunity, hanging out on stage with Gwen!
