Eddie Montgomery, one half of country duo Montgomery Gentry and brother of singer John Michael Montgomery, announced in a press release Thursday that he is battling prostate cancer.

"Yes, rumors have started. And the truth is I have recently been diagnosed with prostate cancer," Eddie writes. "I will be undergoing surgery to remove the cancerous tumor in December. I will be back in January ready to rock for all the fans! Please keep my family and I in your prayers."

Throughout their 11-year career, Eddie and his Montgomery Gentry partner, Troy Gentry, have charted more than 20 singles, including the No. 1 hits 'If You Ever Stop Loving Me,' 'Something to Be Proud Of,' 'Lucky Man,' 'Back When I Knew It All' and 'Roll With Me.' In 2009, Eddie and Troy became members of the Grand Ole Opry and picked up the American Music Awards' Favorite New Artist in the country category. The following year, Montgomery Gentry walked away the winner at the Country Music Association Awards for Vocal Duo of the Year, winning the same honor at the Academy of Country Music Awards that year.

Montgomery Gentry are currently on tour in Canada. The duo will wrap their 2010 schedule up in Charlotte, N.C. on December 4 when they play the ACC Fan Fest.
