Gwen Stefani and Zuma's Cold Water Park Play Date

Out spending some one on one time together, Gwen Stefani and her son, Zuma, were spotted having an afternoon play date at Cold Water Park in Beverly Hills, CA on Monday (June 4).

The mommy son duo looked to be having a great time as they were seen swinging on the swings and playing on the playground while proud momma Gwen looked fabulous sporting her bright red lip and taking pictures of her little man.

The "No doubt" songstress has been spending lots of time with her sons lately and even took them along to a charity event this weekend. On Sunday the beautiful blonde took both of her sons, Zuma and Kingston, A Time For Heroes Celebrity Picnic in Los Angeles.

The fun charity event, which offered carnival games along with arts and crafts, also went to a great cause benefiting the Elizabeth Glaser AIDS Foundation as well as the Wadsworth Theater.
