Brooks Nader’s risqué style finally hit a wall, ’cause daytime TV wasn’t having any of it — forcing her to scramble last minute for a wardrobe swap before the cameras rolled!

We spotted Brooks striking her signature poses before ‘GMA’ Tuesday morning in a cleavage-popping minidress that left very little to the imagination — but when she reappeared post-interview, she was draped head to toe!

Brooks swapped into a classic white tee and blue jeans — still stylish, but fully covered — and joked to us the switch was ’cause, well … her boobies were doing the most for morning TV.

And truth be told, she crushed the second look so hard we had to ask — is her ex Gleb Savchenko eating his heart out? You gotta hear her response!
