Gwen Stefani Celebrates Mother's Day With Gavin And The Kids!

Despite reports that their marriage is on the rocks, Gwen Stefani and Gavin Rossdale looked like the picture of happiness as they escorted their darling sons Kingston, 5, and Zuma, 3, to a fancy birthday party in LA, on Saturday afternoon.

The No Doubt singer looked rock star-chic in an all black ensemble paired with red boots and a tailored jacket she designed herself, while hubby Gavin kept it casual in cargo pants and a tee. Kingston displayed his passion for fashion by wearing a shirt that said "Working Class Hero," paired with camo pants and cowboy boots, while little bro Zuma rocked a Laker's tee, a studded belt and jeans -- they're such a stylish fam!

It's hard to believe Gwen and Gavin have already been married for a decade, and it wasn't until early this year that they've been "fighting nonstop" and have begun marriage counseling to save their union. After it was revealed in 2004 that the Bush singer had fathered a daughter, Daisy, with a former lover, Pearl Lowe, their marriage became strained, according to multiple reports.

The couple has yet to respond to the allegations, but their rep issued a statement calling the breakup “completely untrue,” and that the pair “are not divorcing.”
