Dawson, 29, also took to Instagram to share the news, captioning the same image, "The love of my life is now OFFICIALLY the love of my life. Never been happier. :)."
The couple will have just a couple days to celebrate privately. Pope is expected to make an appearance at the GRAMMYs, where she is nominated for Best Country Duo/Group Performance for her 2016 duet with Chris Young, "Think of You."
ET caught up with Pope in December 2015, where she gushed about another couple, her Voice coach Blake Shelton and his girlfriend, Gwen Stefani.
