Carrie Underwood backs bullied fitness trainer

Carrie Underwood just came out to support her trainer Erin Oprea, who was bullied during her son's soccer game.

The 32-year-old singer's trainer recently attended her son's soccer game, where she decided to get in a quick exercise during parts of the match, reports E! Online.

Criticising Oprea, a man posted a picture of her back and captioned, "Would it be wrong of me to tell her that every dad at the soccer field thinks her standing out front with her jump rope for two hours only screams she wants attention. And I can only imagine what the soccer moms are thinking."

However, standing up in her trainer's support Underwood took to the social media and wrote, "Way to go, Erin! Use someone else's negativity to help others. That man obviously has a big problem...with himself. I only hope he can learn to like himself someday so he can be an adult and stop bullying others for bettering themselves!"

"This guy felt the need to post this pic of my friend and trainer, Erin Oprea, along with some really insecure and mean comments. He was shaming her for getting in some exercise during her son's soccer game. Not cool," her post further read.
