Gwen Stefani worries Gavin Rossdale will miss the birth of their second baby

Gavin is gearing up for a world tour to promote his new solo CD, Wanderlust.

"Gwen is miffed that Gavin didn't have the album's release date pushed back," says a source. "She put her career on hold to spend time with him and their 2-year-old, Kingston, and she doesn't feel like Gavin is holding up his end of the bargain."
