Summertime happiness! Lana Del Rey is secretly engaged to boyfriend Barrie-James O'Neill -- and has been since the warmer months, multiple sources tell Us Weekly exclusively.

The "Summertime Sadness" singer, 27, became engaged to O'Neill -- who sings and plays guitar in the Scottish band Kassidy -- last summer. (Del Rey's rep didn't respond to requests for comment.)

Del Rey and O'Neill reportedly began dating in 2011. The couple sparked engagement rumors in July 2013 when they were photographed house-hunting together in L.A. with Del Rey wearing a diamond sparkler on her ring finger.

Though the retro-glam New York native typically sings about loss in her broody, atmospheric songs, Del Rey noted to Complex magazine in January 2012 that her "Off to the Races" track on her Born to Die album is about euphoric love.

"When I found somebody who I fell in love with, it made me feel different than I felt the rest of the day. It was electrifying. That's what inspired the 'Off to the Races' melodies," she explained. "That's one of the times when you're feeling electrified by someone else and they make you happy to be alive."
