Miranda Lambert pulled a Hilary Swank at Sunday's Grammy Awards.
While accepting a trophy at the L.A. bash, the "House That Built Me" singer made a glaring omission among her many thanks: Her fiance Blake Shelton, who beamed from the audience!
"I forgot!" a mortified Lambert, 27, explained in the press room backstage.
Lambert and Shelton, 34, plan to tie the knot this spring.
"I'm looking forward to getting married -- just doing it," she told UsMagazine.com last year. "Just taking that next step and becoming a woman and moving on in life."
