So late last year she mentioned feeling overwhelmed about life stuff and then in one of her charity highlights she mentioned a cancer charity that was helping someone close to her. So part of me thinks there is stuff going on behind the scenes and she's not coping with it. But the other part of me wonders if she's doing this 'break' to drum up more pregnancy speculation/engagement with people messaging her to ask if she's ok. Even if she was taking a break because there was stuff going on surely the best way to message that would be 'signing off for the weekend and taking some time off after that - see you soon'. I'm all for people taking breaks from social media but when it's your job and you're like Lily (who never opens up to her fans about stuff) I think there is a better way to deal with it.
I don't think she's going on holiday - the only trips she goes on are gifted and no one will be gifting her a stay abroad right now.
