After four years of union, Miranda Lambert and Blake Shelton announce they’re obtaining a divorce.

The couple announced their divorce Monday after four years of marriage.

Shelton proposed in 2010, and they wed the following year, on May 14, 2011, in Boerne, Texas.

Shelton became a judge on NBC’s singing competition The Voice in 2011, and Lambert’s Platinum record won a Grammy for best country album earlier this year.

The Country Music Association has named Shelton and Lambert its male and female vocalists of the year for the last five years, with Shelton winning entertainer of the year in 2012.

The pair won song of the year awards from both the CMA and the Academy of Country Music for Lambert’s 2012 hit Over You, written in regards to the passing of Shelton’s brother.

In 2013, after a tabloid magazine questioned the stability of the marriage, Shelton tweet Lambert, saying, “I only read in a tabloid our marriage is falling apart!” Lambert tweeted back: “Oh no! Can’t wait to read if we make it or not.”

Asked regarding the status of her marriage a year ago, Lambert told USA TODAY, “I am joyful. Youare going to need to inquire Blake how he feels.”
