UPDATE: According to a rep for LeAnn Rimes, the Instagram site purporting to belong to Eddie Cibrian is a fake. "Eddie has never had an Instagram account," the spokesperson told Us Weekly. "This is an imposter and we are taking the necessary steps to shut it down. The postings are bogus." 

 

Eddie Cibrian apparently doesn’t seem to mind his furthering his image as first-class jerk.
 
In the book Drinking & Tweeting and Other Brandi Blunders, ex-wife Brandi Glanville wrote extensively about the heartbreak following the revelation Eddie cheated on her with multiple women, ultimately ending their marriage over an affair with country singer LeAnn Rimes (his co-star in the 2009 TV movie Northern Lights).
 
With the release date of the book approaching, Eddie seems to have no problem taunting the Real Housewives of Beverly Hills star via Instagram.
 
A photo surfaced last week of Eddie and LeAnn holding shots of alcohol with the caption, “Drinking and instagramming whattttttttt my new book title.”
 
Whether the Instagram account is actually his or not is up for debate, but it does contain some pretty personal photos of Eddie and his sons — and tons of pics of him with LeAnn, of course.
 
LeAnn herself bluntly addressed the topic via Twitter earlier today, writing, “Eddie doesn't have an Instagram nor tweet so there.”

Seems like she’s on top of the Brandi gossip almost as fast as we are! Obsessed much?
