Lady Gaga loves her meat in every form ... even couture!

The sexy "Marry The Night" songstress hit the stage in Tokyo wearing a short dress made from cuts of beef.

Back in 2010, Gaga showed up to the 2010 MTV Video Music Awards rockin' a meaty creation made by designer Franc Fernandez.

No one can ever say to Gaga ... where's the beef? We KNOW the answer.
