sunglasses Gavin Rossdale  Gwen Stefani lollipop park ride go karts pregnant jeans

Pregnant Gwen Stefani and hot hubby Gavin Rossdale enjoyed Halloween festivities when they took their boys, Kingston and Zuma, on a weekend trip to Lake Arrowhead, Calif. While on the mini vacay, the family of four (and soon to be five!) -- visited Lollipop Park where the gang rode rides and played games together. We can't get enough of this adorable family!

On Sunday, the musical couple took the kids to visit the park and had some good old fashioned scary fun. The day before, the Stefani/Rossdale clan got in the Halloween spirit when they all headed down to the pumpkin patch and enjoyed the local sights.

Of course the No Doubt singer stepped out for all of the weekend's events in some rockin' duds. For the outing, Gwen and Gavin bundled up in matching oversized sweaters and jeans. The 43-year-old paired her comfy look with Tory Burch hi-top sneakers.

Sounds like a fun and stylish weekend!
