The singers wed in front of 550 of their closest friends and family Saturday at a San Antonio ranch.
Clarkson gushed about the reception Sunday, taking to her Facebook page to talk about her friends.
“So I went to Miranda and Blake Shelton’s wedding last night and it was the greatest wedding/reception I’ve ever been to,” the 29-year-old singer wrote.
Lambert, 27, wore her mother’s wedding dress as she walked down the aisle to marry Shelton, 34.
The couple has been dating since 2006.
