The 27-year-old Grammy winner announced her engagement to Hurd, 32, on social media by posting a series of photos in which she flaunted her new accessory.
In one of the photos, Morris appeared to be sitting on Hurd's lap while holding a Corona Light and resting her hand on her fiance's leg.
Another picture showed the couple gazing into each others' eyes, which Morris simply captioned, "Yes" with an engagement ring emoji.
The two began dating in December 2015 and were friends for years.
