Lady Gaga Wears White Bubble Machine Dress + Heels in London [PHOTOS]

Lady Gaga is back. Not just because she opened the iTunes Wireless Festival with a crazy performance on Sept. 1. But because she has resumed wearing neck-breaker heels and outrageous outfits, like the white bubble machine dress she wore post-performance. It was like a geometry problem come to life.

She's worn a bubble dress before, but this one seemed to make real bubbles, meaning there was a mechanism inside the frock to help create them. We wish we were kidding.

Does that shoulder antenna connect her to social media via clothes in addition to pushing out bubbles? Could be.

Yes, dahling, you look faboo.

But how do you sit in that thing?

From the back...

How does she walk in those? They defy understanding.

Walk, walk, fashion baby! Sudsy, too!

Eye contact! Is she a human washing machine?

Gaga, really, what's going on with that dress, girl? It's a bubble making machine!

She also wore a square shouldered black coat, which, when paired with those stripper heels, showed off her shapely legs.

What's underneath that thing? Is she an exhibitionist? We kid, we kid. But notice Gaga is rocking her natural hair. No wigs!
