Vanderpump Rules was already filming when LVP's brother committed suicide. RHOBH had not yet begun to film but the contracts were already signed. It was Bravo that approached Lisa, and said she could take a hiatus from either show or both. LVP is the one who chose to continue filming VPR and chose to film RHOBH. During VPR, Teddi went to SUR to ask Lisa if her brother could interview for a job at any of her venues inclusive of the not yet open TomTom. LVP's brother had already committed suicide and Teddi was comforting her. LVP made sure to point out on camera she only took 7 days off for her brother, because she is a serious business woman.
IMO, LVP should just have continued filming VPR - she could have advertised all of her bar/restaurants from there. The cast of VPR would not really get into her personal business - what she says goes over there, subjects she doesn't want discussed would not be discussed over on VPR. She wouldn't have the same control over on RHOBH.
Did anyone notice she made an announcement that she was returning to film VPR - there was of course a plug for the Vegas venue which I just heard is totally tanking.
