Her long-standing feud with the woman who split up her marriage to Eddie Cibrian has been well-documented.

But Brandi Glanville wasted no more than three minutes before launching into an expletive rant about LeAnn Rimes on Tuesday night, as she arrived to make her mark on the British version of Celebrity Big Brother.

Speaking to MailOnline before entering the Celebrity Big Brother house on Tuesday, Brandi called Eddie dumb before dropping the f-bomb and even the c-word when referring to LeAnn, on the live opening night.

The wait is over: Brandi Glanville made an explosive entrance into the Celebrity Big Brother house on Tuesday night, in London

When asked how she would feel if Eddie should join her on the show, she said: 'He's so dumb. I see him all the time. He makes my skin crawl.

'When someone sleeps with someone else they are no longer attractive to you. All that is gone.'

Eddie and Brandi were married from May 2001 - September 2010 but he cheated on her with LeAnn in 2009. They then married in 2011.

Harsh words: Brandi said she didn't tell her ex-husband Eddie Cibrian and his new wife LeAnn Rimes about her reality TV show appearance

Turning heads: She was not only turning heads with her appearance, but also with her foul mouth

Brandi and Eddie's children, Mason, 14, and Jake, 10, will stay with him and LeAnn while she's on the show, but she says they will NOT be backing her to win.

'No, they won't be rooting for me,' she said. 'They don't even know I'm doing it and you can't really watch the show in America anyway.'

'They normally have the children for a week at a time, so it's just a couple of weeks more. It's no big deal.

'I'll more than make up for it afterwards with a nice holiday for the boys.'

As a sign of things to come, Brandi launched into an expletive tirade against her love rival within minutes of filming for the Channel 5 show.

She said: 'My ex-husband married a c***,' she exclaimed. 'I don't have a drinking problem, I have a f**king drinking solution.

She continued: 'Drink rose all day and go f**k yourself. I'm very f**king angry.'

Brandi was a major star of reality show, The Real Housewives Of Beverly Hills, until she left the show in 2015 - later having to deny she was fired.

She said: 'This show will be a different experience to Housewives. There was a lot of yelling and it was explosive.

'I'm not saying there won't be any of that. It does happen, I won't lie.

'I am wild but I am also calm as well and I've got a nurturing side, so it will be nice for people to see that side of me. Drama just finds me.'

Brandi famously slapped Lisa Vanderpump on Real Housewives in 2015 and has be known to throw the occasional glass of wine in temper, but she claims those days are more than likely, a thing of the past.

She told MailOnline: 'I mean, that's just wine abuse. I won't be doing that again. Why waste the wine?'

The leggy blonde was replaced by Dorit Kemsley on the show, but she's not bitter about it at all.

She said: 'Oh, you can't replace me, honey. You can get a new character. But I just hit a wall with that show. It was so stressful, I needed a break.

'I was anxiety-ridden. Everyone was fighting. I was depressed.'

Brandi also spoke about her former flame Calum Best, 36, and said he had no good advice to offer her about Celebrity Big Brother, despite going on the show himself.

'We do keep in touch, but he would only say how full on it is and he had no other words of wisdom,' she said.

Famously feisty, she has clashed with some of the leading stars of the programme, including Lisa Rinna, Kyle Richards and Lisa Vanderpump.

However she is perhaps best known for the cheating scandal that plagued her relationship with Eddie Cibrian, who was seeing now-wife LeAnn at the same time that he was married to Brandi.

Brandi and Eddie share two sons, Mason and Jake, for whom country music singer LeAnn now serves as step-mom.

Brandi's feud with LeAnn is ongoing and worsened this year when Brandi entered into her first relationship since the scandal, with a man she met on Tinder, Donald 'DJ' Friese.
