Celeb reactions to the star studded inauguration, featuring Lady Gaga, JLo and glorious, magnificent coats

Inauguration Day finally arrived Wednesday, with Joe Biden being sworn in as the 46th U.S. president, alongside Kamala Harris as the first Black, Indian and female vice-president at the start of the star-studded affair.

Due to the pandemic, the socially distanced ceremony only has about 1,000 guests, including former presidents Barack Obama, George W. Bush and Bill Clinton. While Mike Pence was in attendance, Donald Trump was not, making himself the first president to skip a successor's inauguration since Andrew Johnson, natch.

In a resplendent Hunger Games-esque look (mockingjay brooch and all), Lady Gaga sang the national anthem, followed by Jennifer Lopez in an all white ensemble, singing a passionate medley (and squeezing in a conspicuous "let's get loud" refrain), and Garth Brooks with "Amazing Grace."

Others set to perform throughout the day include Bruce Springsteen, Foo Fighters, John Legend, Jon Bon Jovi, Justin Timberlake and more.

Here's a peek at how social media and Hollywood are taking the news:

More than anything, it seemed, it's the coats that have all of Twitter up in arms. That, and Bernie Sanders (and his coat).

And yes, Chrissy Teigen has been mercifully and hilariously tweeting throughout, as she awaits for husband John Legend to perform:
