Justin Bieber

The show must go on for Justin Bieber—even amid frightening circumstances.

The pop star hit the stage Wednesday night in Atlanta, just hours after it was revealed that two fugitives conspired to strangle and castrate the 18-year-old as part of a gruesome murder plot.

Biebs appeared anything but unfazed, performing at Power 96.1's Jingle Ball at Philips Arena, where he tore into hits like "Baby" and "Beauty and a Beat" while decked out in red harem pants and a bandana. (He didn't get to hog the spotlight for long, though: Ke$ha and Flo Rida also took the stage.)

Big-ups to Biebs for being the ever-consummate pro.

Here's what else went down:

Fascinating! Barbara Walters revealed her most fascinating person of 2012. A clue: It wasn't Honey Boo Boo.

A Storm of Support: Stars came out en masse (including Kristen Stewartsurprise!) for a good cause at the 12-12-12 Concert for Sandy Relief.

Brawl Fallout: Gabriel Aubry's arraignment stemming from his dustup with Olivier Martinez has been canceled; instead, an office hearing has been scheduled.

Romance Takes Flight: Renée Zellweger stepped out with a mystery man at LAX.

Monster Mash! Check out the new trailer for the monsters vs. robots extravaganza Pacific Rim.
