The ex-England captain had the new inking done with his youngest son Cruz, 18.
David, 48, already has a “Victoria” tribute on his arm, plus his four kids’ names.
He showed The Sun his new tattoo ahead of next week’s Who Cares Wins awards where he was surprising a nominee in West London.
Cruz has also had “Posh” emblazoned across his arm.
The Sun revealed how last month supporters were dreaming that Inter Miami supremo Becks would land a signing almost as incredible as Lionel Messi’s arrival.
The ex-England skipper’s wife Victoria posted loved-up snaps from Sipan, off the coast of Modric‘s native Croatia.
But for once fans seemed more interested in transfer gossip than talk about one of sport’s most famous couples.
That’s because Beckham was pictured chatting earnestly with Real Madrid maestro Modric as the duo sat in their swim shorts on sun-loungers.
The former Manchester United midfielder, 48, lent over and appeared to be pressing home a point, whereas the 37-year-old gazed away into the distance.
