cannes france Antibes gavin rossdale sunglasses

Gavin Rossdale and son Kingston, 3, are too cute at the Eden Roc hotel in Cannes, where they're staying for the Cannes Film Festival. The father and son sport matching outfits, and little Kingston is all smiles with his papa!

Kingston and Zuma, 2, waited at the hotel for mommy Gwen Stefani to arrive. And she did - in style! The designer/singer worked a long, flowing dress.

Papa Gavin kept a watchful eye on the beautiful blond boys as they played by the balcony of their room, and later on some rocks by the water. Kingston must be excited for the Pirates of the Caribbean: On Stranger Tides showings at the fest, because he sported a hook and an eye patch!
