Brandi Glanville has put an expiration date on ex-husband Eddie Cibrian’s marriage to Leann Rimes. In a new interview on E! News’ Daily Pop, the “Real Housewives of Beverly Hills” alum said she is confident her estranged ex will leave his second wife high and dry sometime within the next three years.

Glanville, who has been vocal about Cibrian’s philandering ways (the former “Sunset Beach” star previously had an affair with “Vanderpump Rules” star Scheana Shay), predicts the actor will spend "three more years" with the wealthy country music singer before leaving her. Brandi says that once the marriage hits the 10-year milestone, “half of everything is his and then he's gone.”

The former couple’s messy history

Brandi Glanville was married to Eddie Cibrian from 2001 to 2010 and they have two sons together, Mason and Jake.

The couple’s nine-year marriage ended after Cibrian hooked up with Rimes on the set of the TV movie “Northern Lights.” At the time, LeAnn was married to Dean Sheremet, so two marriages ultimately ended in the aftermath of the affair. Eddie Cibrian and LeAnn Rimes tied the knot in 2011.

Glanville says her relationship with Cibrian and Rimes is “rocky” right now. Brandi and LeAnn have regularly aired their grievances about one another on social media. But Brandi is banking on the fact that her kids’ “bonus mom” will be out of their lives for good in a few years. "[Once] the 10-year mark comes and he leaves her and takes half her stuff, we'll all be good together because they won't even be related. If she doesn't have a kid with him, then we don't ever have to see her again,” Brandi told E! News.

From ghetto rich to sugar mama

Brandi Glanville has long accused LeAnn Rimes of being Eddie Cibrian’s “sugar mama.” In a 2013 interview on Bravo’s “Watch What Happens Live,” Brandi told host Andy Cohen that Eddie had always aspired to live in a big house with a gated community, a dream that was fulfilled thanks to Rimes’ wealth.

Brandi Glanville previously told the UK publication The Sunday Times that while her ex-husband loved to mingle with the rich and famous during their nine years together, they were never “truly rich.” Glanville described their façade as “ghetto rich,” revealing that while they had “the nice cars, the nice house and the nice jewels,” they also had a second and a third mortgage and were living paycheck to paycheck with no money in their savings account.
