A few weeks back, Victoria posted a minion transfer on an unnamed body part of her husband claiming young Harper had given her dad a tattoo. One can only assume that inspired David to get a proper tattoo to celebrate his youngest child.
He captioned the below: "Hey Pretty Lady.... Just adding to the collection of tattoos that mean so much to me... Thanks Mark as always looks amazing ... @shamrocksocialclub." That's in LA in case you were thinking of knocking in to get inked.
That bit of body you're looking at above is his neck; between this and the other tattoo he got celebrating the year he married Victoria - '99 - he's running out of room.
If they ever break up it'll be a very sorry day for marriage everywhere.
