Tonight is the Billboard Music Awards, live from the MGM Grand in Las Vegas! Which raises questions such as “Why does Billboard throw its awards show in May?” and “Who will be there?” To answer your first question, when ABC brought the show back in 2011 after four years off the air (it aired on Fox in the more reasonable month of December from 1989 to 2007) the goal was to put an awards ceremony in the spring, when there are no other awards shows. As for the second question: Ludacris is hosting. Hologram Michael Jackson is doing a song from Xscape. Ariana Grande and Iggy Azalea will perform instant Stereogum favorite “Problem,” Robin Thicke will sing a song designed to win back his estranged wife, and awards show mainstays Lorde and Katy Perry will take the stage. Notable collaborations include Miley Cyrus covering the Beatles with her new buds the Flaming Lips, Jason Derulo joining forces with Snoop Dogg and 2 Chainz, and a duet by reality show contestants-turned-country superstars Carrie Underwood and Miranda Lambert. Also hitting the stage will be recent The Week In Pop subjects John Legend, Shakira, and 5 Seconds Of Summer. Presenters include Wiz Khalifa, Pete Wentz, Shania Twain, Kelly Rowland, and Jack Antonoff of Fun./Bleachers. We’ll update below with anything interesting.

The first notable performance of the night came from Grande, Azalea, and Charli XCX, who tacked an abbreviated “Fancy” onto the front end of “Problem.” Watch that below.

Later, a montage preposterously compared 5 Seconds Of Summer’s Stateside arrival to that of the Beatles. Then the American-Apparel-underwear-lovin’ Aussie pop-punk boy band made their US TV debut while humorously rocking Misfits and Pink Floyd T-shirts:

Despite all the hyperbolic fanfare for 5SOS, Kendall Jenner had a little Adele Dazeem moment when it came time to introduce them.

Then it was time to debut a hologram of early ’90s MJ doing “Slave To The Rhythm,” an all-around creepy, cynical, and underwhelming endeavor.

Lorde, who already won two awards tonight, stopped by to perform “Tennis Court.”

In a performance recorded earlier tonight in the UK, Cyrus, Wayne Coyne, and Steven Drozd bashed out a rendition of “Lucy In The Sky With Diamonds” that rivaled the original in terms of mind-wrecking potency.

Also our friend Joe Mande was there for some reason!
