LeAnn Rimes takes jab at husband's ex-wife with racy booty picture

LeAnn Rimes sure knows how to make a point!

The 33-year-old singer threw major shade at "Real Housewives" star Brandi Glanville in the best way possible -- with a smokin' hot Instagram photo.

Glanville first posted a revealing photo with the caption, "Dear a*shole, this is no longer yours. Bye."

The 43-year-old reality star wore a purple thong that accentuated her long legs and perky backside. It's clear the eyebrow-raising message was directed at her ex-husband, Eddie Cibrian.

Of course, Rimes, who's currently married to Cibrian, couldn't keep quiet. Four hours later, the country crooner responded with a scandalous picture of her own.

Rimes proved her love for America in a red, white and blue bikini that showcased her voluptuous booty as she casually laid on the grass. Shortly after, she shared a selfie with her hunky man.

While the photos seem harmless, there's a lot of history between the blonde bombshells that make it anything but.

Rimes and Cibirian met on the set of a movie made for television called "Northern Lights" in 2009. Rumors sparked they were having an affair.

Shortly after Glanville filed for divorce in 2010, the pair got married. Since then, the animosity between the women has been obvious on social media.

Recent comments by Glanville made it seemed like they've buried the hatchet.

"We have to be a unit, the three of us," Glanville said in a SiriusXM interview. "We are a modern family, and we have to stick together in order to keep these little boys in line and to keep them from not manipulating us against each other, and we need to be together for them."

But after their latest booty exchange, it looks like we may have been jumping to conclusions.
