The Daily Mail reports that Lisa Vanderpump's mother, Jean, died suddenly at the age of 84 this week, and that the reality star has halted filming of Vanderpump Rules indefinitely as she travels to London to make funeral arrangements. A source tells Page Six that the 58-year-old Vanderpump is "very shocked" by her mother's death "because her grandmother lived to almost 100." Jean's death comes after Vanderpump's brother, Mark, died in April 2018 of a suspected drug overdose at his home in England.
