Showstopper! The former Real Housewives of Beverly Hills reality star flaunted her sculpted stems in a revealing cutout minidress

'Do you remember when we were playing pool in Canada?' the 43-year-old is heard asking Dean. 'I mean, like, vividly.'

'It's weird that you say that moment because that was the moment that I knew that it was kinda, it was it,' Sheremet, 35, admitted. 'That was a very, very bizarre thing and it was the beginning of the end.'

Brandi uttered: 'I just got the chills, there were other things but in that moment, in time is when it all, I was like, "Holy f**k, this is happening." '

'And it was so bizarre to me because I knew it but I didn't want to believe it,' she continued. 'And I feel like you were kind of in the same boat, maybe?'

Revealing! Glanville donned the see-through garb which included several sheer cutouts, including those around her chest and neckline

Dean replied: 'Yeah, I think when you're in that space, and I don't think I wanted to believe it up until the point when I signed my divorce papers, you didn't want to believe it.'

Eddie, 42, was previously married to Glanville from 2001 to 2010 and they have sons Mason, 12, and eight-year-old Jake together.

LeAnn, 33, and Eddie met on the set of the Lifetime television movie Northern Lights and fell for each other while she also was still married to Sheremet.
