With all the back and forth shenanigans between these two, you would think the year was still 2011. Instead, it's 2015 and LeAnn Rimes and Brandi Glanville just can't stop throwing shade at each on their social media accounts. This time around the country singer is being criticized for a message she wrote on Mother's Day, implying that her job as a mother to Eddie Cibrian's kids Mason and Jake is just as important as their biological mother's.

According to Celebitchy on Tuesday, Rimes wrote, "a parent is the most rewarding yet challenging job anyone could ever have. Happy Mother's Day to every kind of mother there is. To every woman who thinks they're completely screwing it up at any moment. To every woman who's giving it their all and loving from the deepest places in their hearts they never knew existed. I hope you're celebrated and appreciated not only today, but everyday. #proudmemberofthestepmomclub #happymothersday"

Many commenters wrote, "She is so hateful and insecure. And crazy. Let's not forget crazy," along with, "I wish these three would just bury the hatchet and SHUT UP- they have two kids in the middle of this craziness, who asked for none of this."

Another commentator wrote, "Good Lord, why are they so obsessed with each other still?!"

In the past, Rimes has been accused of setting up photo ops with the paparazzi at Mason and Jake's soccer games in order to portray a "happy family" image between her, Cibrian, and the kids.

Rimes and Cibrian tied the knot back in April 2011, following their alleged cheating scandal while they were still married to other people.
