Miranda Lambert Weight Loss, Follows Blake Shelton Cheating Rumors [VIDEO]

Miranda Lambert is looking slimmer after stepping out in the wake of husband Blake Shelton cheating rumors.

Lambert was photographed at the 61st Annual BMI Country Awards on Nov. 6 looking much slimmer than her appearance in 2012. In Nov. 2012, the country singer was looking curvier in a sand-colored dress at the 46th Annual CMA Awards.

At Wednesday's BMI Country Awards, the actress wore a black dress that showed off her skinnier figure.

Lambert and Shelton are in the middle of a series of rumors that accuse both spouses of cheating on each other. The rumors began when the National Enquirer tabloid published a story detailing their infidelity. The story claimed that Shelton has been spotted getting close to a pair of young country girls. They also claimed that Lambert has carried on with several men.

Shelton joked about the rumors on his Twitter account in late October, tweeting, "I just read back to back NEW stories that @mirandalambert and I are having a baby, divorcing, cheating and feuding with @cher. Must be true!"

Lambert has not addressed the rumors on her own Twitter account.

Both Lambert and Shelton are nominated at the CMA Awards, which will be aired Wednesday night at 8 p.m. on ABC. Lambert is nominated for Single of the Year, Female Vocalist of the Year and Music Video of the Year. Her song Mama's Broken Heart is nominated for Song of the Year as well.

Shelton is nominated for Entertainer of the Year, Album of the Year, Male Vocalist of the Year and Music Video of the Year. Additionally, Shelton's song Boys 'Round Here is nominated for Musical Event of the Year with Lambert's band Pistol Annies.
