"Real Housewives of Beverly Hills" reality star Brandi Glanville might be civil with former husband, Eddie Cibrian, and LeAnn Rimes but underneath, she's seething because the couple is "living the life."

During her podcast on Sunday, Brandi Glanville, 42, revealed, "I broke into his house yesterday but he gave me permission because I had to get my son's moonsuit."

Accordingly, it was the first time for Brandi Glanville to set foot in the house after Eddie Cibrian left her and the kids for much younger LeAnn Rimes.

She said, "I'm like, 'This f----- is living the life. I was pissed, but that's a whole other story. My [ex] husband doesn't work. He's an actor, but 90 percent of Hollywood's out of work, so he's not working. So I fit the bill for everything with my children."

"In case you live in a bubble, Eddie cheated on Brandi with LeAnn after he met the country singer on set of their Lifetime movie 'The Northern Lights' in 2009," said In Touch Weekly. "The now exes - who were married from 2001 until 2010 - have two children together, Mason Edward, 11, and Jake Austin, 7."

If the "Real Housewives of Beverly Hills" reality star is pissed because her ex, Eddie Cibrian, and LeAnn Rimes are living the life, she should refrain from checking out the country star's Instagram. Just two days ago, LeAnn Rimes shared a photo of their vacation in Mexico and also in Montana.

There's a lot of tension between Brandi Glanville and LeAnn Rimes over Eddie Cibrian, but lately they seem to be civil towards each other.

In a Twitter post last month, for instance, "Real Housewives of Beverly Hills" star Brandi Glanville even gave a shoutout to LeAnn Rimes and Eddie Cibrian for supporting her cause.

Brandi Glanville tweeted, "Thx for sponsoring me on my "WALK for WISHES* Eddie and @leannrimes please RT https://shar.es/1fiWHe to your followers to Grant More Wishes!"
