The advantage of only two official inaugural balls? An early night.

The Obamas got back to the White House Monday night a little after 10 p.m., which left them plenty of time to celebrate at a private, late-night bash in the executive mansion for top donors, staff, and several selected celebrities. The exclusive party was not covered by the White House press, but John Legend, Katy Perry, and Kelly Clarkson were among those helpfully tweeting out news.

The first lady kicked things off, wrote Clarkson shortly after midnight: “Just partied at the White House. . . I kid you not, Michelle Obama stood up and got the party started. . . seriously cool First Lady :). Ashley Judd called it “a magical night,” was emotional (“I took my mama to the white house & every step I took I wanted to cry”), and Legend wrote, “It’s a celebration!” at 2:30 a.m and posted a picture of himself and fiancee Chrissy Teigen in the East Room.

“I don't even know what to say,” tweeted Teigen. “It's 3:15am and I just teared up seeing our president getting down at the white house.” It was Perry who gave the definitive thumbs up: “All other parties from here on out will be judged unless they take place at the White House.”

And no, there’s no such thing as a private private party anymore.
