Kendall Jenner, J.Lo, Demi And Everyone Else Was At Big Sean’s Show Last Night

Demi Lovato, Kanye West, JLo And Everyone Else Was At Big Sean's Concert Last NightPre-Grammy parties are notoriously packed with A-list names, but Big Sean's set for Yahoo! Live on Saturday Night at the House of Blues looked like it was trying to set some kind of record. OK, maybe we're exaggerating just a bit, but the Instagram pictures coming in from the afterparty were pretty epic.

We haven't seen anything snapped by Sean's lady Ariana Grande from the show, but J.Lo and Demi Lovato made up for her in the pop-star department. Kendall Jenner was there too. J. Cole, Justin Bieber and Chris Brown were on the scene, only to be out-frowned by Kanye West.

Big Sean surrounded himself with big boss talent in a photo with Ye, Jay-Z, Nas, and a couple of dudes who aren't quite like the others. That's Steve Stoute, record-exec-turned-marketing-CEO who wrote The Tanning of America; and Robert Kraft, who owns a little team called the New England Patriots. Because after your team wins the Super Bowl, you might as well go hang out with Kanye and J.Lo.

The show wasn't short on talent either. According to Vibe, Big Sean (who's on Kanye's G.O.O.D. Music label) was joined onstage by Yeezy, Bieber, J. Cole, Meek Mill, DJ Mustard, Tyga, Chris Brown, Ty Dolla $ign and YG. Take that, Clive Davis party.
