Miranda Lambert isn't letting her divorce keep her from singing. The 31-year-old and husband Blake Shelton announced earlier this week that after four years of marriage they had decided to call it quits.

The "Little Red Wagon" singer took the stage Wednesday in her first post-divorce performance. According to Us Weekly, she joined close friend Ashley Monroe in concert to celebrate her album release. The country music besties performed a beautiful duet of "Has Anybody Ever Told You," which Nashville Country Club captured on video on Instagram. The publication reports she did the show without her wedding band.

Although she is back to performing, Lambert canceled a show around the time her now ex-husband filed for divorce. On July 9 she canceled a show in Calgary, Canada citing vocal cord inflammation as the cause. Us Weekly noted, however, that the show's scheduled date coincided with Shelton's filing. Lambert apologized to fans and promised to reschedule.

Shelton has also headed back to work since the split. The 39-year-old confirmed he was back on set of "The Voice" in a tweet on Wednesday, joking about bringing "a full ice chest" in with him. The tweet was just one of several comedic messaged Shelton has sent since going public with the divorce news. Lambert, however, has stayed silent. Both have removed photos of one another from their social media profiles.

As we previously reported, Shelton and Lambert released a joint statement confirming their split on July 20. In it they told fans it was "with heavy hearts" that they had decided to go their separate ways. At the time of the statements release the couple's divorce, which is said to have taken just two weeks to process, had been finalized.
