Blake Shelton made sure Mother's Day was exactly what his wife Gwen Stefani needed. He and her three sons, Kingston, 16, Zuma, 14, and Apollo, 9, spoiled the matriarch of the family with gifts and dinner. "It was a pretty laidback day. Me and the boys, we got her some flowers, and candles and the boys made her some things. Just tried to spoil her a little bit," Shelton tells Access Hollywood. "But then we all went out for a dinner," he continues. "It was a pretty laidback day, but we tried to celebrate her. She works hard." Which Hollywood couples are your favorites and why?
