Kyle Richards breaks down in TEARS while filming new season of RHOBH with Dorit Kemsley - amid friendship rough patch and THAT Mauricio Umansky split

Kyle Richards was seen having an emotional breakdown as she filmed the latest season of Real Housewives of Beverly Hills with co-star Dorit Kemsley on Saturday.

The 55-year-old reality television personality — who was spotted on a lunch outing earlier this month — appeared to be reduced to tears during a one-on-one conversation with Kemsley, 47.

The castmates were shooting a spa-themed segment of the Bravo series and each wore luxurious white robes and slippers with their names monogrammed on them.

It comes as Richards and Kemsley navigate a rough patch in their years-long friendship and follows news of Dorit's split from husband PK Kemsley.

Bravolebrities Erika Jayne, Garcelle Beauvais, Sutton Stracke and Jennifer Tilly were also present for the day of filming.

It comes weeks after Kyle's estranged husband Mauricio Umansky 'moved out and into his own luxury condo.'

Richards also recently dropped the Umansky name from her social media profiles.

Richards and Umansky, 53, split last year after 27 years of marriage, with the RHOBH star revealing on the reality show that her ex was looking for a new home.

Kyle shares daughters Alexia, 27; Sophia, 24; and Portia, 16, with her ex. She also has daughter Farrah Aldjufrie, 35, from her previous marriage to Guraish Aldjufrie.

Us Weekly recently reported that Umansky purchased a luxury condo in a new development in West Hollywood.

A second source said: 'Kyle and Mauricio have been living separately for the last few months and he’s been staying there.

'They’ve both been traveling a lot recently, so it’s working out where they don’t stay under one roof.'

It was added that Umansky 'will visit their primary residence often' when Richards is out of town.

In February, Kyle said that Mauricio was still living with her in their San Fernando Valley family home, but confirmed that they slept in 'different rooms.'

When she was asked if there's a chance that she and Mauricio will get back together, the mother-of-four replied that she was unsure.

'I really don't know what my future holds right now, to be honest, which is the weirdest part of all of this,' she said at the time.

Season 14 of The Real Housewives of Beverly Hills resumed filming weeks ago.

Dorit was spotted filming the latest installment of the franchise in mid May.

The star was heading into castmate Erika's house days after she and PK announced their separation following nine years of marriage.

Dorit and PK posted a joint statement about their separation on May 9 after Bravo reportedly threatened to downgrade her to a 'friend' of the Housewives if she didn't admit she and her husband were living separately.

PK has been residing at the Beverly Hills Hotel for some time now, according to insiders.

Being a 'friend' on the series, instead of a regular cast member, would reduce Dorit's appearances to just three episodes in the entire season.

'She really does not want to be seen as a single mother in Beverly Hills, because once you are labeled that you don't get invited to as many parties, you lose friends, you aren't an insider,' a source told DailyMail.com, adding that PK has all the social ties.

'He has a lot of celebrity friends and pull, so she doesn't want to lose him at the end of the day,' the source said.

'And it's not just about power. She also does not want the world to know she failed at her marriage.'

Kyle, who had a falling out with Dorit after Season 13 finished taping, weighed in on Dorit's situation during an Amazon Live on May 15.

'I feel bad for them. Obviously, you know, going through that is difficult enough without everybody wanting to know all the details,' she said.
