Two starving dogs fighting over an old bone couldn’t compare to the endurance of rivals LeAnn Rimes and Brandi Glanville!

The women continue to trash-talk one another in the press or social media whenever an opportunity presents itself.

This time it is LeAnn Rimes firing shots at her 41-year-old nemesis.

The 31-year-old singer was recently gushing on Twitter about Madison, Glanville’s daughter with ex-husband Eddie Cibrian.

“Heading to the rink for daughter’s skating competition,” tweeted Rimes. She later added “Goooood luck to her!”

Rimes also shared that she was planning a birthday party for son Mason.

As both Madison and Mason are Glanville’s birth children, some suspect that Rimes’s blabbing isn’t merely about her happy family life.

As the younger woman who swooped in and took Glanville’s family away from her, some even suspect the constant updates by Rimes are her way of quietly reminding her bitter rival of all she’d taken.

One of Rimes’ followers seemed to suspect as much, writing the following message to the star:

“I’m not meaning this in a mean way. Do you think a bit of the hate would dwindle, if you were to not mention the kids as much?”

Rimes would have none of it. She responded by saying, “No! They are my life Eddie and my life revolve around them I will not edit myself because of anyone else’s childishness.”

The dig at Glanville was more than apparent as the Real Housewives of Beverly Hills star has expressed her unhappiness in the past about Rimes being so close to her own children.

“You think your heart is broken after you get a divorce? Wait until there is a girl tweeting pictures of, ‘Oh, look at my family'”, said Glanville during an interview in March. “You have no idea.”

In a comment directed at Rimes, the indignant reality TV star said, “You can have the man, but those are my babies.”

It looks like neither woman is prepared to give an inch, even for the sake of providing stability to the very children they’re squabbling over.

Do you think Rimes is entitled to constantly talk about Glanville’s children? Do you think there are ulterior motives behind the tweets? Comment below!
