After a camo-filled trip outdoors celebrating Kingston's 10th birthday, his mom (Gwen Stefani!) took him backstage to see her boyfriend, Blake Shelton, perform! But, not before they jumped on a private helicopter to the show!

Stefani is documenting their fun trip on the mobile app Snapchat and the above video is just too sweet! She's definitely a "cool mom" — wouldn't you say?

The Voice coach's eldest son spent Friday riding a dune buggy and playing with frogs. They even went fishing together!

The following day, they went on an exhilarating ride in the sky before the annual Firestone Legends Day Concert where Shelton is currently headlining — just one day before the historic 100th Running of the Indianapolis 500 in Indianapolis, Indiana.

Stefani is also mom to Zuma, 7 1/2, and Apollo, 2, with ex-husband Gavin Rossdale. Stefani and Rossdale divorce was settled on April 8.

Happy Birthday, Kingston!
