Lisa Rinna was also on hand to dish out the thousands of hot meals, even managing to look glamorous in full make-up.  

The 52-year-old reality television star posed for the cameras dressed in a Santa hat and red apron, and managed to snap a couple of pictures on her cell-phone. 

She was slammed by Yolanda Foster on Tuesday after remarking on this week's RHOBH that the mother of Gigi and Bella Hadid may be faking Lyme disease. 

Lisa suggested to Kyle Richards and Lisa Vanderpump that the former model might be faking the symptoms for attention.

The former Days Of Our Lives actress grew sniffy about Yolanda’s social media output.

‘I feel that Yolanda’s posts on Instagram can be confusing, because one minute she’s in a hospital bed with needles in her arm and the next she’s on a yacht looking like she’s having a great time,’ said Lisa.

The Melrose Place actress then read a description of Munchausen syndrome or ‘factitious disorder’ – where people feign illness to gain attention or sympathy.

In her blog post after the show, Yolanda said several friends had reacted angrily to Lisa's remarks, but she rose above it, claiming 'I am not enraged or affected anymore by what I have learned to see as human nature and the weak side of it'.

'I do wonder though why these adult women sit around drinking wine in the afternoon debating another person’s health issues?' she asked. 'As much as I wished they cared enough to learn and ask questions, I must blame it on and assume it's "ignorance".'

Pause for thought: The celebrities had a chat during a quick break
