Giorgio Armani certainly shook things up at the 2010 Grammys.

The silver-haired fashion maestro custom-designed Lady Gaga's entire 2010 Grammys wardrobe including her Armani Privé red carpet number -- an iridescent dress with NASA-worthy swirling orbits paired with an intergalactic "Edward Scissorhands"-worthy weapon accessory.

Add her wacky, crystal-studded wedges and you've got, well, another out-there Lady Gaga look to keep sartorial tongues wagging.

Then, for her show-opening duet with Elton John, the "Poker Face" singer channeled a neo-Tinker Bell in a super high-cut bodysuit (can you say Brazilian bikini wax?) complete with ultra-arched shoulders and matching green glitter booties.

On the designer selection, the over-the-top pop star was all accolades: "I am honored to be wearing Armani this evening. The series of pieces Mr. Armani created for me are truly iconic; they represent not only beautiful fashion, but my spirit and essence as an artist.

"Mr. Armani is a fashion legend, and tonight would not have been the same without his touch, and his wonderful team," Gaga said in a release.

While the performer has put her stamp on outlandish fashion, for her first ever Grammys, we'd think a sci-fi look by Alexander McQueen or a goth-princess getup by Givenchy before a collaboration with the more classic and understated Armani.

But perhaps Giorgio is out to prove that despite rumored retirement plans, he's still got his finger on the fashion pulse.

"We hear Lady Gaga's music everywhere we go. It is like a soundtrack of our times," the 75-year old designer said in a statement. "In addition to her formidable songwriting skills, she is a modern fashion phenomenon. I am delighted to be creating these outfits on such an important night for her, the Grammys, and I wish her the best of luck."

We'd say this red carpet and onstage score with Lady Gaga earned Armani some serious fashion-forward style cred.
