Blake Shelton and Miranda Lambert are calling it quits after four years of marriage.
"This is not the future we envisioned," the couple Monday. "And it is with heavy hearts that we move forward separately. We are real people, with real lives, with real families, friends and colleagues. Therefore, we kindly ask for privacy and compassion concerning this very personal matter."
The country singers tied the knot in Texas in 2011 after dating for six years.
Both remained mum on social media about the split leading up to the announcement, with Lambert tweeting about an upcoming show just hours before the statement's release Monday afternoon.
The famous pair – who recently played an Independence Day weekend show together – have weathered rumors of relationship troubles for years, which Shelton, 39, addressed in a 2013 PEOPLE cover story.
