Gwen Stefani and Gavin Rossdale are raising some very cultured children.

The entire family was in attendance at the opening of photographers Steve Erle and Pete Black's Exposure 2 Photo Exhibit on June 28, at Siren Studios in Los Angeles.

Despite reports earlier this year that the couple's marriage was heading for divorce , eyewitnesses say the family looked very happy at Thursday night's event.

"Gavin wouldn't start walking around without holding Gwen's hand," a source told People magazine . "They couldn't have been sweeter. They were playing with their kids the entire time and [seemed] so doting. Kingston was embarrassed getting his photo taken. It was very cute. Zuma was laughing and his dad was holding him."

Making time for fun events with the entire family has to be difficult for Stefani, 42, who has been hard at work recording her band No Doubt's sixth album, Push and Shove, which is due out July 16.
