Earlier today, we reported on the sad news that Lisa Vanderpump's mother has passed away at the age of 84.

The death of Jean Vanderpump comes just one year after Lisa's brother, Mark Vanderpump, committed suicide.

The news also closely follows closely on the heels of reports that Lisa has quit The Real Housewives of Beverly Hills in response to a falling out with her fellow cast members.

With all of this going on, it's not surprising that Lisa will be stepping away from the spotlight in order to return to England and be with her family.

Unfortunately, that means she'll miss a major social event that's sure to factor prominently in both the lives of her close friends and the eighth season of her eponymous reality show.

Jax Taylor and Brittany Cartwright are set to get married next weekend, and Radar Online is now reporting that Lisa will not be in attendance.

“Lisa will not be able to go to the wedding,” says one insider.

While Jax and Brittany are said to be disappointed by the news, they have reportedly expressed their support for her decision.

The source claims that Taylor and Cartwright have not yet spoken to Lisa in person, but have contacted her via text message.

“They have reached out to send their condolences, and accept she needs to step away from filming the show right now so she can attend to her family," says the insider.

Lisa was also scheduled to be a guest of honor at World Pride events in New York on June 30.

Sadly, she will be forced to miss those events, as well.

“Lisa loves and supports the LGBTQ community, but knows that they will understand,” says the tipster.

The insider goes on to say that Lisa is at the lowest point of her life after losing two immediate family members in such rapid succession.

“She’s absolutely devastated at losing her mother when she is still grieving over the loss of her brother,” says the source.

Stars and colleagues alike have offered their condolences to the reality star and restaurateur, but we're sure words are of little comfort at this time.

All the same, our thoughts are with Lisa during this tremendously difficult time.

We hope she takes all the help she needs and finds support wherever she can.
