Cilla 'ere!!
Haven't seen any mention of the nice chap that Louisa is pictured with on a couple of her IG posts. May well be a relative, friend or colleague, or could it be a new partner? Is this the reason that Jack seemed to have such a sudden and unexpected meltdown on the same day that Louisa was flying out for a nice weekend break? I know nothing about her relationship history, so she could easily be bisexual or had / having a bit of a midlife experiment. Everyone is free to have whatever relationship feels right at different times of their life, so there is no reason why it should be assumed that her next partner will be female. Part of me is of course saying this is none of my business, but they are of a similar age and do seem very happy together in the photos.
