Her fractious relationship with Christine Quinn has been an integral storyline on Selling Sunset.
And Mary Fitzgerald, 39, has revealed she can’t see things changing any time soon, as she is still struggling to rebuild her friendship with her co-worker, 31.
Speaking exclusively to MailOnline, Mary – who has partnered with celebrity shout out app Thrillz to provide personalised messages for fans – confessed things are still rocky between the pair.
Realtors at war: Selling Sunset star Mary Fitzgerald, 39, has revealed that she is still struggling to rebuild her friendship with her co-worker Christine Quinn, 31, after a series of rows
Discussing their tumultuous relationship, Mary revealed: ‘It’s been intense! Even more than what viewers got to see.
‘We are in a better place now, but we’re not best friends, and we don’t hang out all the time. We actually don’t talk all that much but we’re both living our own lives’.
While Mary and Christine are two of the most successful realtors at The Oppenheim Group, their sales have often been overshadowed by the drama going on behind the scenes.
Tension: Speaking exclusively to MailOnline, Mary confessed things are still rocky between the pair and that she doesn’t want any negativity in her life
As fans will remember, Mary inadvertently landed in Christine’s crosshairs as she prepared to tie the knot with her now husband, Romain Bonnet.
Christine took issue with Mary not inviting her friend and co-worker Davina Potratz to the nuptials, and was also insulted to learn of a second Bachelorette party that she had not been invited to.
Defending her decision to keep Davina off the guestlist, Mary mused: I have to stand by my man! That caused some some difficulty for sure – to put it lightly…’
Tensions between the stars also boiled over when Mary suggested that Christine and her millionaire tech husband Christian Richard had started dating while he was still with his ex, something they both denied.

Stating that Christine can be ‘extreme’ to deal with, Mary said: ‘what you see is what you get. But that’s the thing, she is very extreme.’
She continued: ‘I used to live with Christine so I know her very well. When she’s at home, she’s chill, but when she goes out she’s very over the top.
‘But that’s who she is. She’s – not in a bad way – but got two personalities.
‘I’m not trying to say anything terrible but she’s super extreme, and if she gets mad… you guys see what she does! I think that’s something she needs to work on.
‘She’s a very nice person, but she can be brutal… It’s something I just have to step back from because I don’t want that in my life’.

However, the pair haven’t completely given up on each other, as Mary revealed: ‘We’re finding our way. We have to make an effort to talk to each other.
‘We’re not at that point, I don’t think yet, but but we’re both looking forward to getting back to solid friendship.’
Mary and Christine’s ongoing drama will no doubt play out on season four of Selling Sunset, which has not yet begun filming due to the coronavirus pandemic.
The Netflix show showcases the drama at The Oppenheim Group, where brokers sell the luxurious life to affluent buyers, with plenty of drama going on behind-the-scenes.
Having been thrust into the spotlight with the series becoming an overnight success, Mary has had to deal with the downsides of fame.
Boasting over a million Instagram followers, and 16,000 on Twitter, the realtor has experienced her first experiences with trolling.
Yet Mary tries not to let it keep her down, reasoning: ‘I’ve been pretty lucky. I don’t get it as much as some of the other girls get it.
‘I typically don’t respond to any negativity, but there have been a couple where I couldn’t not.
‘I kill them with kindness and a couple times like they’ve just like been shocked. They’re like, “I’m so sorry, like I didn’t really think you would actually respond. And you’re right. I’m going through something myself. And this is why I’m doing this.”‘

She continued: ‘Listen, I feel bad for you if you really feel the need to put this much negativity out there for someone that you don’t even know.
‘I hope you get through whatever it is you’re going through, because you’re obviously projecting your hardship or negative experiences on to someone else. I wish you nothing but healing!
‘That’s the only way I typically respond, but it takes me a while. It has to be six months of non-stop negativity before I’ll even acknowledge it, because I don’t think you should ever acknowledge it really.
‘For the most part people are very, very supportive.’
Mary is also keeping busy as one of many Hollywood stars who work with Thrillz, a site that allows fans to commission personalised video messages from celebrities.
Speaking about her work with the platform, Mary enthused: ‘I think it’s fun to be able to interact with with fans.
‘Anytime I get a chance to do something like that I think it’s great. If it’s something that makes them happy. I love it.’
Revealing that her celebrity status still hasn’t sunk in, she added : ‘It’s insane that I have fans!’
