The half penny Lady said that Lydia and Ali have a big anniversary coming up. They got married in 2017, 6 years is not a big anniversary!!
I am not convinced just yet it is a full vowel renewal as surely Fi would know about it, no way would Lydia and Carrie be able to keep it a secret. I think they may do a new photoshoot incorporating the new fake lifestyle.
Her over the top shrieking and asking if she gets another hen do seems like she is just messing with Fi to get engagement.
