While you'd imagine it might have something to do with the fact that she's rumoured to be worth a whopping $130million of their combined $150million fortune, it's apparently not actually her own wellbeing that Miley's worried about.
Yep, apparently she's given puppy love a whole new meaning and is more concerned about the future of her and Liam's pack of doggy pals.
“Miley is worth over $130 million and has no plans to lose her nest egg in case of divorce,” an insider apparently told Life & Style.
“She has a half-dozen dogs that are her babies - she doesn’t want to lose them.”
To be fair, if the rumours about all this are true we can't help thinking she might have the right kind of idea.
It's not like she's even got a bag full of hair extensions to keep her puppies warm now she's had it all shaved off. Wonder if any celebs would have her back...
