Lisa Vanderpump 'jokes' about Eileen Davidson's husband having 'his head up somebody's skirt' on RHOBH 

Lisa Vanderpump enraged Eileen Davidson yet again on Tuesday's episode of The Real Housewives Of Beverly Hills by suggesting her husband was being unfaithful.

The British restaurateur 'joked' that Eileen's husband Vincent Van Patten was 'in the corner with his head up somebody's skirt'.

'I don't think so,' snapped Eileen who was attending a party at Dorit Kemsley's house with Lisa, 56, and the rest of the RHOBH cast.

'I do hope that I didn't offend her, ish,' sniggered Lisa sarcastically afterwards.

'I don't think this ''British humour'' is exactly what she says it is, I think it's a little loaded,' moaned Eileen.

The party had started sedately, with Vanderpump chatting to LA Galaxy soccer star Robbie Keane.

But things were still frosty between Eileen, Lisa Rinna and Lisa Vanderpump.
