Ash London confessed to Katy Perry this week that her husband has had to put a ban on how many times she obsessively plays new track 'Never Really Over' in the house.
The chorus is a bit of a tongue-twister with Katy Perry admitting you really have to study it to pull it off.
Without missing a beat, Ash launched into her attempt at the chorus... which even Aussie Pop Prince Troye Sivan gave his praise to!
Maybe Ash can collab with Troye when he's here in September?
