Lady Gaga singer performance today show blonde Lady Gaga singer performance today show blonde It may have been raining in New York this morning when Lady GaGa, wearing a very Madonna-ish white suit and bra combo, performed for Today's summer concert series, but that didn't stop GaGa from drawing an enormous crowd of almost 18,000 people!

She IS the most popular living person on Facebook, after all!

GaGa started out singing the jazz standard Someone to Watch Over Me before launching into Bad Romance. And if a free GaGa performance wasn't enough of a reason to stay in the soaking ran, GaGa rewarded her fans with New York pizza sent to the crowds courtesy of GaGa herself.

Check out her amazing live performance below:
