Blake Shelton and Miranda Lambert each earn 4 CMA Award nominations

But the common number of nods wasn't all the Tishomingo residents wound up sharing when the 2012 CMA Awards nominations were revealed Wednesday.

The country music power couple are nominated together for song of the year for Lambert's heartbreaking hit “Over You.” The song of the year prize is awarded to songwriters.

The pair, who wed in 2011, penned the emotional ballad about the death of Shelton's older brother Richie in a car accident. Blake Shelton was just a teenager at the time, so his wife never met his brother.

“‘Over You' means so much to me and to my husband and to our family,” Lambert said during the June CMT Music Awards, where “Over You” earned the female video of the year trophy.

Shelton and Lambert are among the few married couples to share a CMA song of the year nod. Ed and Patsy Bruce were nominated in 1978 for “Mommas Don't Let Your Babies Grow Up To Be Cowboys.” Sanger D. “Whitey” Shafer wrote “Does Fort Worth Ever Cross Your Mind” with his third wife, Darlene Shafer, in 1985 and “All My Ex's Live in Texas” with his fourth wife, Lyndia Shafer, in 1987. Tammy Wynette and George Richey, who wed in 1978, wrote the 1976 nominee “'Til I Can Make It on My Own” with Billy Sherrill.

Along with song of the year, Shelton earned a shot at the CMA Awards top prize, entertainer of the year, along with Jason Aldean, Kenny Chesney, Brad Paisley and current titleholder Taylor Swift.

The Ada native also is nominated for male vocalist of the year, an award he won the past two years, and single of the year for his chart-topping ballad “God Gave Me You,” produced by Scott Hendricks. Plus, contemporary Christian singer-songwriter Dave Barnes received a song of the year nomination for penning “God Gave Me You.”
