It was a family day for Gwen Stefani  and Gavin Rossdale  at a charity benefit in LA yesterday. The couple took their kids, Kingston and Zuma, as well as Gwen's niece Stella, to the Elizabeth Glaser Pediatric AIDS Foundation event. They weren't the only celebrity babies at the bash as Tia and Tamera Mowry both brought their little ones to the fundraiser.
Gwen and Gavin's children are no strangers to mixing with celebrities at parties — the whole family attended producer Joel Silver's famous Memorial Day beach party in Malibu  last weekend, where the kids played on an inflatable slide on the sand and hung out with stars like Sean Penn  and Diane Kruger .
