The 39-year-old country singer, who finalised his divorce from the blonde beauty this week just hours after confirming he quietly filed court documents seeking to dissolve their four-year marriage in Oklahoma two weeks ago, is reportedly attempting to keep busy on the set of 'The Voice' USA before the filming wraps up later this week.
A source close to the 'Sangria' hitmaker told PEOPLE.com: ''He's devastated, but he's been really private about it. He's focused on the job and has been as engaged and friendly as he has always been.''
Miranda, 31, is also trying to focus on her career and is preparing to perform in Nashville next week.
The former couple have been plagued by allegations of cheating, but it was also recently claimed they decided to suddenly separate because she wasn't ready to have children.
A source previously said: ''He is eager to have children, but she really enjoys not being tied down. I think they both were off on what the time frame would be.
''They are never together, and he was wanting them to move close to being together. She really loves her career and touring. She has the ability to go and record albums when she wants and to tour.''
