It looks like the hate triangle between LeAnn Rimes, Brandi Glanville and Eddie Cibrian will never end. Despite endlessly bashing Glanville in their new VH1 reality show, there are new reports that say Rimes "played nice" with Glanville during son Jake's fifth grade graduation recently.

Did LeAnn Rimes Give Up On Getting Pregnant?

Apparently, Glanville tried to keep her distance away from the couple, but it was Rimes who would sit next to her and try to make small talk with her in front of everyone at the ceremony.

"Leann went out of her way to say hello and goodbye to Brandi, and even sat right across from her and tried to talk to her," a source tells Radar Online. "But she refused to look at LeAnn in the eye and only gave half a-- responses."

LeAnn Rimes Emotionally Hurting Eddie Cibrian's Kids?

It seems as though tensions are still high in Rimes and Cibrian's new reality show, where they blame Glanville for spreading false rumors about Cibrian's employment situation and their marriage.

Just last week, Glanville reportedly played Carrie Underwood's Before He Cheats at her son Mason's birthday party as a subtle jab to Rimes and Cibrian.

Cibrian was married to Glanville for ten years before he cheated on her with Rimes in 2009. The couple later went on to marry in 2012. In their new reality show, which is still untitled, Cibrian and Rimes expose their personal life to the cameras, where they talk about the gossip fodder about their marriage, their battle with Glanville and Rimes' infertility issues. VH1 has not yet announced an air date.
