Miranda Lambert showed that she is on the mend when she returned to the stage Wednesday for the first time since divorcing Blake Shelton. The “Over You” singer looked gorgeous, wearing a little black dress and cowboy boots. She joined best friend Ashley Monroe at Nashville’s The Basement to celebrate her album release, singing a duet of Monroe’s song “Has Anybody Ever Told You.” The 30-year-old country singer wore her short hair straight and accessorized her all-black ensemble with a long necklace, bracelets and some rings. Noticeably absent, however, were her diamond engagement ring and wedding band. This marked Lambert’s first public appearance since she and Shelton announced their split Monday in a joint statement.
