Lady Gaga is known for wearing showstopping outfits, but her choice in accessories at last night's Oscars may have taken the cake for her most expensive look.

The first film Gaga has starred in, A Star is Born, was up for eight nominations last night, and won for Best Original Song for the movie's chart-topping hit, "Shallow."

The Joanne singer donned a sleek black dress, gorgeous retro updo, and black gloves for her 2019 Oscars red carpet look. And as stunning as her look was, fans were more focused on her necklace--which casually costs a reported $30 million.

That's right. Gaga showed off a Tiffany diamond last night at the show, which costs roughly as much as the entire budget for the movie she starred in, according to W Magazine.

But wait, there's more. The last time the bling was worn was in 1961 by Audrey Hepburn while doing press for Breakfast at Tiffany's. Gaga's overall look seemed to call upon Hepburn, from her gloves to her updo, so it made sense to add the iconic accessory.

Fans on Twitter were quick to point out where many other millenials may recognize the design from--early 2000's rom-com How to Lose a Guy in 10 Days.

Other fans opted to hilariously reference another box office hit this year, Ocean's 8, and the presence of some of its actresses at the awards.

While we don't think Sandra, Awkwafina, or Anne Hathaway would try anything, it would sure put more focus on to Gaga's bling than ever before. She certainly served a look last night.
