Gavin Gets Support from Gwen & the Boys

Gavin Rossdale performed in Chicago on June 26 with band Bush at the 30th anniversary of the Taste of Chicago. There to support Gavin was wife Gwen Stefani and their two sons Kingston and Zuma. Little Zuma, the younger of the two boys, proved to be Dad's number one fan as he tried to run towards Gavin while Gavin performed onstage.

A nanny was there to help Gwen with a tear-filled Zuma. Big Brother Kingston, on the other hand, just enjoyed the show from Mom's lap. However, he was almost equally entertained by the rainbow slinky brought along.

Gwen's loose fitting shirt is feeding the rumors that Gwen is expecting baby number three! With Kingston stationed on her lap, it's hard to get a good look at her baby bump. We're sure Gavin would love another member added to his little backstage fan base!

This concert marked one of the first for Bush since going on a hiatus in 2001. Gavin recently announced that, in addition to this performance, you can expect to hear a new album from Bush, as well as a tour! We can't wait to hear it; we're sure it'll be worth the wait!
