The 29-year-old singer has been betrothed to "Chicago Fire" star Taylor, 34, for a year now following his Valentine's Day proposal with a heart-shaped diamond ring in 2015 -- which came one week after last year's Grammys.
But just because matrimony is in the cards, it seems Gaga has no intention of dressing like your average housewife anytime soon. Proof: Her wild outfit at the Feb. 15, 2016, ceremony where she wore a custom-made Marc Jacobs ensemble that resembled Ziggy Stardust with a long blue coat that had sparkles, rainbows and colorful patches. She wore a bodysuit underneath and had a high slit to show off her legs for days. She paired the long coat with red satin pumps that tied around her ankles, and her bold look was complete with a bright orange wig as well as sparkly blue eyeshadow.
Before she walked the red carpet, she shared an Instagram while she was getting her makeup done, and she was tearing.
As for tonight, all eyes are on Gaga -- but not just for her fashion! She will perform a touching tribute in memory of David Bowie, who died on Jan. 10, 2016, after a 18-month battle with cancer.
For her tribute, Gaga partnered with Intel as part of the "Experience Amazing" campaign to show how technology facilitates unique experiences through the world. She teased her performance in a video for Intel and said, "With the arsenal of the world's leading technology at my fingertips, I now have the ability to invent the un-inventable." She added that the collaboartion with Intel will "culminate in a performance that inspires to remind the world of the seed of innovation, the wizard behind the curtain, the mind behind the machine."
And the six-time-Grammy-winner is also nominated for "Best Song Written For Visual Media" for her song "Til It Happens To You" from the documentary film "Hunting Ground."
One big question that Lady Gaga has yet to address is when her wedding is taking place.
The singer -- whose real name is Stefani Joanne Angelina Germanotta -- and Taylor are remaining mum on wedding details, but Taylor Kinney did recently speak to "In Touch Weekly" about the rumors that they're getting married in Italy.
"I heard that I was getting married in Italy. I want to know if I can go," he joked. "Do I get to come to this thing? It sounds like an amazing party—I want to go!"
Gaga, who performed the "Star-spangled Banner" at the Super Bowl earlier this month, started dating Taylor in 2011 after meeting on the set of her music video "You and I."
Before she started dating Taylor, in 2010, Gaga was not a stranger to rocking outrageous fashion at the Grammys. She wore a space-age Armani Prive dress that looked like its own planet. One year later, she showed up to the award show in a giant egg that was carried by four men and one woman.
She did not stop to do interviews on the carpet, but her creative director Lori Ann Gibson spoke to Ryan Seacrest at the time. "Lady Gaga is incubating," she explained. "Lady Gaga is in embryonic stage and won't be born until her performance this evening." That night, she performed her hit "Born This Way."
In 2012, Lady Gaga did not walk the red carpet but was seen in the audience wearing a very unique look. Her custom Versace dress was composed of black fake leather and featured a rhinestone black veil that not only covered her entire body but also covered her face in what looked like fishnet. She also had a metallic gold bodice with sharp shoulders and held onto a matching gold scepter.
More recently, Lady Gaga stunned on the red carpet in 2015 when she wore a glittery silver custom-made Brandon Maxwell gown. The show-stopping style featured a high slit and a plunging neckline, which showed off cleavage and an emerald Lorraine Schwartz necklace. She was even dubbed a modern mermaid.
