Barefoot LeAnn Rimes Knocks Brandi Glanville During Live Show

By Jon Boon - RadarOnline.com Reporter

LeAnn Rimes staged a bizarre barefoot performance at a concert in California and couldn't wait to give Brandi Glanville a jab.

The 30-year-old country star appeared Wednesday night at the Civic Arts Plaza in Thousand Oaks clad in a figure-hugging leather dress in front of around 1,800 people where she kicked off her heels and sat down on a rug on stage during the end of the show.

And LeAnn couldn't help but aim a dig at the expense of The Real Housewives of Beverly Hills star. She mumbled to her audience: "Anybody ever been pissed off at some point and you just couldn't get it out. And if you did, you actually might dig yourself a deeper hole, so you just let the other person dig themselves a hole?"

Glanville, her ex-husband Eddie Cibrian and his wife LeAnn have been feuding over whether one of their kids ate a laxative belonging to LeAnn thinking it was candy.

As RadarOnline.com previously reported, the warfare started after concerns of parenting for Brandi and Eddie’s two sons, Mason and Jake.

"People around Brandi started getting vocal a few weeks back about their worries concerning her parenting of the boys," a source close to the situation told RadarOnline.com.

"Numerous different people told Brandi, 40, that they were concerned that when she had her sons with her she wasn't paying enough attention to them and was distracted with everything else going on in her life."

And in an explosive interview with Us Weekly, Brandi ripped into LeAnn alleging that Rimes has a "severe eating disorder" and that Mason became "extremely ill" after accidentally ingesting one of LeAnn's laxatives.

In an email sent by Eddie to Brandi he accused her of being consumed with "wine and narcissism" while she shot back taunting him on Twitter to "find ur balls" and "MAN THE F**K Up eddie put the tequila down and be a proper parent.
