David Beckham -- The #1 Underwear Model of the Century ... Says Tommy Hilfiger

One package to rule them all ... and that package belongs to David Beckham ... so says Tommy Hilfiger who tells TMZ Sports the soccer icon is the GREATEST male undie model of all time.

This clip is actually pretty great ... it starts with our photog asking Tommy for a modeling job -- and in what may be the nicest "Don't call us" moment of all time, Tommy sings Beckham's praises as the "Underwear model of the century."

The interesting part -- Beckham never modeled for Tommy ... in fact, DB only ever modeled for the competition (Armani, H&M).

So ... sorry Mark Wahlberg ... and Antonio Sabato Jr. ... and Mehcad Brooks -- but when it comes to Tommy's pick -- you guys just didn't measure up.
