Last night was all about actors, actresses, directors and the film industry at large having their moment of glory — and in some cases, their glory suddenly revoked due to embarrassing accidents. But once the long (very long) ceremony was over, it was all about our favorite pop stars yet again.

Tons of our favorite radio darlings — from Katy Perry to Diplo to Sia to Demi Lovato — made their mark at the Vanity Fair Oscars party in Hollywood following the awards show, showing off their red carpet-ready best.

In some cases, pop stars served double duty — including Janelle Monae and Justin Timberlake — as both nominees for the evening and party-goers.

Check out all the musicians who hit the red carpet at the night's hottest after-party up top.
