Celebrities were spotted yesterday in both New York City and LA celebrating Halloween with their kids.

Just like us, they toted them to Halloween parties and out trick or treating.

To add to the fun, many of them dressed up along with their kids and created a family theme!

Here are some highlights (in order):

• Isla Fisher and daughter Olive Baron Cohen (pictured left)
• Christina Aguilera and son Max Bratman
• Gwen Stefani and Gavin Rossdale with sons Kingston and Zuma
• Alyson Hannigan and Husband Alexis Denisof with their baby ‘Joey’ Satyana
• Brooke Shields with daughters Grier and Rowan Henchy
• Ed Burns, Finn Burns and Grace Burns
• Marcia Cross and Tom Mahoney with daughters Eden and Savannah Mahoney
• Jon Stewart and his wife Tracey with kids Nathan and Maggie
• Deborrah-Lee Furness with kids, Ava and Oscar Jackman

With just a few days left to get ready for Halloween, the Rossdales dropped by LA’s famed Pumpkin Patch, Mr. Bones to pick out the perfect pumpkins to carve for the big night.

Kingston ran around the patch slaying pumpkins in his Lightning McQueen costume, while Zuma was content to hang out with his parents.

With a nanny and a couple ride-ons in tow, Gwen Stefani enjoyed the afternoon playing around in the dirt with her two sons, Kingston and Zuma Rossdale.

The fashionable mom threw it back to the 80’s in her paint splattered harem pants. Do you remember them? She really can pull anything off!

Gwen Stefani and hubby Gavin were seen enjoying a relaxing day at the beach yesterday with kids Zuma, 1, and Kingston, 3.

The family seemed to have a great time as they alternated from splashing in the ocean to playing on the beach before loading up the car and calling it a day.

Gwen Stefani took time out of her tour schedule to visit the beach at Dana Point in Laguna Niguel with her hubby and their two sons Kingston and Zuma.

The proud parents took turn snapping pictures of each other with their boys enjoying the water.

Gwen and NoDoubt will play 4 concerts over the next 5 nights in the area.

Gwen Stefani took time out of her busy tour schedule to take sons Kingston and Zuma out sightseeing in Washington DC. Included in her stop was a tour of the White House. Now that Washington DC is a hot spot with President Obama in office, celebrities are adding extra time on their stays in the city to take in the sights.

Gwen Stefani and husband Gavin Rossdale took their children Zuma and Kingston to Gwen’s parents? house in Los Angeles for Easter dinner.

Starting May 2nd, Gwen re-unites with No Doubt to tour for the summer. I wonder if the kids will be her roadies?

While Gavin Rossdale gave a free concert outside at the Nokia center this morning, his adorable son Kingston sang along on a mic at the side of the stage.

Gwen Stefani and her two children, Kingston, 2, and 6-month-old Zuma, cheer on daddy at The 5th Annual K-Swiss Desert Smash Charity Celebrity Tennis Event at the La Quinta Resort & Club in Palm Springs.

Gavin recently revealed that he and his wife bathe together in a bid to save water and help the environment.

He insisted that every family should adopt the same technique to do their bit for the environment.

“All families should bathe together. It’s the least they could do!” Gavin said.

Meanwhile, Gwen revealed that she and Gavin have a new nickname for Kingston because he is currently going through a troublesome stage.

“Kingston is in that terrible twos. Gavin calls him Sid Vicious. He’s like, ‘You gave birth to Sid Vicious.’ He’s definitely got an attitude and Zuma is the opposite. He’s like this cool, laidback, easy-going guy – is that always how it is?” Gwen said.

Here is a picture of the smiley baby today in Palm Springs:

Kingston Rossdale braves the elements while out for a ride in London yesterday.

Wrapped up in two hoodies, a thick coat and Wellington boots, Kingston peddled to the shops on his Leonardo DX smart-trike.

This cool trike features a 5-point harness for younger riders that changes to a seatbelt when they get older.

The telescopic parent handle allows the parent to control the direction of travel.

The Rossdale boys always get the coolest stuff!
