The country singer has been dating former CSI: Miami star Cibrian since last year, when they came clean about their affair and split from their respective spouses.
Earlier this week, Rimes released the single Crazy Women, prompting speculation she is singing about Glanville in the track.
She sings, "Crazy women are made by crazy men/ He cheats and lies, then plays the victim/ He don't know why they always pick them/ Crazy women, ex-wives and old girlfriends/ Keep their crazy hidden/ Till they're pushed off the deep end."
Glanville has been left unimpressed with the subject matter of the single, telling E! News, "When your cheating is the cause of a 'crazy woman's' behaviour, it's in poor taste to sing about it."
