The couple, who have been together for five years after meeting on the US version of The Voice, tied the knot on Saturday at Blake’s sprawling Oklahoma ranch.
The Voice host, Carson Daly, officiated the wedding in front of approximately 40 guests in a small chapel at the ranch.
Gwen confirmed she had walked down the aisle with a series of gorgeous pics on Instagram.
The singer wore a stunning Vera Wang wedding dress, which featured a fitted bodice and floor-length tulle skirt.
She wore another strapless Vera Wang gown complete with tulle mini skirt for the evening reception, which featured a pair of hand-sewn love birds symbolising the couple.
Three baby lovebirds also made their way into the dress, representing Gwen’s children – Kingston, 15, Zuma, 12, and Apollo, seven – with ex-husband Gavin Rossdale.
Gwen finished the outfit with a pair of white stiletto cowboy boots.
The chart-topping musicians have released several songs together, including Nobody But You, which reached number 18 on the Billboard Hot 100 last year.
Gwen and former husband Gavin Rossdale, the lead singer of band Bush divorced in 2016.
Blake was previously married to singer Miranda Lambert but they announced they had divorced after four years of marriage in July 2015.
In 2017, he was named sexiest man alive by People magazine.
