Gwen Stefani treats boyfriend Blake Shelton to first trip to Disneyland

Blake Shelton and Gwen Stefani celebrated their one-year anniversary as a couple early with a family trip to Disneyland on Wednesday (12Oct16).

The No Doubt star took her man to the 'happiest place on earth' for the first time as part of a trip home to her native Orange County, California.

The couple was joined by Gwen's three sons and her parents.

Blake got into the spirit of his Disneyland debut by wandering around the themepark with a big smile and a badge that read '1st Visit!'

"As a OC girl born and raised who has a Disney pass I'm FREAKING out," Gwen captioned a shot of the happy group on social media. "@blakeshelton is at Disneyland... Every time he's in Anaheim I have like an out of body experience."

As part of the trip to Orange County, Gwen also showed Blake the Beacon Street house where she and her No Doubt bandmates lived when they were starting out in the early 1990s.

She also visited her childhood home with Blake and her kids.

The two musicians started dating last year (15) after meeting as judges on TV talent show The Voice and falling in love following their respective marriage splits and divorces earlier in the year.
