And while we think it's super posh, others have been wondering WTF it means!
Well wonder no more, because we've got the deets for ya!
Apparently the name Harper is an old english name that's always grabbed Victoria's attention.
And Seven? Well, it's actually special in a number of ways - no pun intended.
It of course represents the lucky number, but it also correlates with daddy's football jersey.
Not only that, but little Poshie was born in the seventh month as well as the seventh hour!
Wow! If anyone assumed they didn't put any thought into it, this should shut them up!
Welcome to the world, lucky spice!
