With their second child due any day now, Gwen Stefani and Gavin Rossdale are making sure their son Kingston, 2, isn't feeling left out.

The pair have been doting on the tot in recent weeks, taking him for trips to the London Zoo and on a shopping spree to Hamleys.

Before leaving L.A. for London on June 23, Gwen, 38, her mom, dad and Kingston celebrated a farewell dinner at Buddha’s Belly restaurant on June 19.

“Gwen was absolutely glowing,” fellow diner Hilary Ratner tells OK!. “Gwen and her family were in the back, relaxing and enjoying themselves. And little Kingston was adorable! He has a lot of energy! His grandpa was playing peek-a-boo with him and walking him around the restaurant. Everyone was charmed.”

The No Doubt frontwoman is due this summer. She and Gavin have not found out the sex of the baby.
