Crazy Ex-Girlfriend is the second studio album by American country music artist, Miranda Lambert, released May 1, 2007, by Columbia Nashville.

"Easy From Now On" (written by Carlene Carter and Susanna Clark) was originally a Top 15 Billboard country hit for Emmylou Harris and appeared on her 1978 album, Quarter Moon in a Ten Cent Town.

[3] "Dry Town" was written by Gillian Welch and David Rawlings but would not appear on any of their albums until 2017's Boots No 1: The Official Revival Bootleg.

Lambert said she drew inspiration for writing such music because both her parents were private investigators and she was frequently exposed to crime scenes.

[5] In an interview with Young Money Magazine, Lambert described Crazy Ex-Girlfriend and how it compared with her previous release.

Lambert clarified that although most listeners view her as a "badass" singer, other songs on the album also show a more mellow-sounding side of her musical artistry.

[7] Stephen Thomas Erlewine from AllMusic hailed it as one of 2007's best albums, demonstrating Lambert's skills as a singer and a songwriter because of her "wry wit and clear eye for little details, mining the unexpected from such familiar subjects as love and loss and jealously and rage.

"[14] Jonathan Keefe from Slant Magazine credited her with defying country music's "historically and presently conservative gender politics" on an album that was "brash, insightful, wry, and, above all else, smart".

[15] Stylus Magazine critic Josh Love deemed it a coming-of-age record for Lambert, who was self-possessed enough to craft "a persona whose power relies not on values, beliefs, or experiences, but on feints, distance, and masterful command ... Lambert is at a very rarified place right now, turning her songs into vehicles for a persona that transcends background narrative and personal history".

[17] It was voted the 15th best album of the year in the Pazz & Jop, an annual poll of American critics published by The Village Voice.

[25] The album was certified Gold by the Recording Industry Association of America on June 2, 2008 for shipment of over 500,000 copies in the United States.

In April, the album's third track, "Famous in a Small Town", was released as the second single, debuting at number 54 on the Billboard country chart.
