Back in December Yolanda Hadid and David Foster announced plans to split, with former officially filing for divorce in January.

And on Tuesday in a preview for an upcoming episode of The Real Housewives of Beverly Hills - shared exclusively by Entertainment Tonight - David, 66, could be heard sharing his doubts about the couple's relationship.

Though he was off-camera in the clip, microphones still picked up a conversation with David's friend Tom, in which he discussed his 52-year-old ex.

The pair didn't seem to realize they were being recorded as Tom asked if David was feeling better, to which he morosely responded: 'A little, yeah. It's been a stretch.'

Caught on tape: In a teaser for an upcoming episode of The Real Housewives of Beverly Hills, David Foster, L, seems to have been caught unaware as he discusses doubts about his marriage to now ex Yolanda Hadid, R

His friend then added that he wanted his life to 'get back to the way it was when you first got together.'

David, however, was not so sure that that was even possible, questioning: 'How's that going to happen?'

Following the tense scene, the teaser - which also shows Yolanda looking to be in good spirits as she mingles with friends - featured the mother-of-three lamenting the loss of David's 'wingman.'

'He married a woman that was a social butterfly, always out, and doing and doing … and then all of a sudden, I got sick,' Yolanda said.

Off the hook: The 66-year-old didn't seem to realize he was being recorded, as for most of the scene he was mainly off-camera, with the shot focusing on Kyle Richards's side of the couch, or on David's now ex Yolanda

Whoops! Despite not being the focus of the shot, microphones were still able to catch the dialogue between David and friend Tom, as the former was asked 'Are you feeling better?'

'And you know, [I'm] the shell of the woman I used to be. Yes, he gets impatient. We've been trying to work through all the ups and downs. This is my journey, but unfortunately, it's out of my control.'

Two months after the scene was shot the former couple announced plans to divorce, sharing a statement with People.

'Sadly we have decided to go our separate ways. We've shared nine beautiful and joyous years together,' the statement said.

Wishful thinking: Tom appears to be more hopeful for David's situation, saying he wants his life to 'get back to the way it was when you first got together'

Doubtful: David, however, is not so sure that that outcome is even possible

Feeling better: The downtrodden clip was juxtaposed with shots of Yolanda looking to be in good spirits as she mingled with friends

'During that time we experienced love, friendship and the inevitable challenges that come with managing a marriage, careers, blended families and health issues.'

The statement also read: 'We are grateful for the years we've spent together and believe wholeheartedly that we did our best.'

Earlier this month Yolanda spoke with Dr. Oz about how her struggles with Lyme disease affected her marriage.

Hard work: In a confessional in the teaser, Yolanda discussed her struggle with Lyme disease, sharing: '[I'm] the shell of the woman I used to be. Yes, he gets impatient. We've been trying to work through all the ups and downs'

Moving on: Two months after this episode was filmed, Yolanda and David (pictured here at the Global Lyme Alliance Gala in October) announced their plans to divorce

'The patient suffers, but the caretakers suffer too,' she shared. 'At the end of the day, David never changed. I changed.'

She continued, of her chronic illness: 'It wasn't a choice, but I'm not the woman I used to be. And I probably never will be again.'
