L ady Antebellum guitarist Dave Haywood pulled out all the holiday stops to propose to girlfriend Kelli Cashiola on Monday night (Dec. 19).
A rep for the country star told PEOPLE that Haywood staged an elaborate scene at Cashiola's Nashville home while she was at work -- Warner Music Nashville, where she is VP of Marketing/Brand Management -- creating a wintry wonderland inside the house and using Christmas lights to spell "Will you marry me?" out front.
The answer: "Yes." Haywood and Cashiola, both 29, have been friends for about five years but only recently stepped out in public as a couple, at various awards' shows including last month's BMI Country Awards.
Lady A's third album, "Own the Night," debuted atop the Billboard 200 when released in September on Warner Music Nashville. Haywood plays guitar, piano and mandolin in the band, which is rounded out by singers Hillary Scott and Charles Kelley.
