Philly Hosts a Star-Studded Jingle Ball

Heading east to help ring in the holiday season, Avril Lavigne, Pete Wentz, Robin Thicke and Austin Mahone headed to Q102's Jingle Ball 2013 in Philadelphia, Pennsylvania on Wednesday (December 4).

The "Sk8er Boi" singer kept things simple in a long-sleeved black top, black skinnies, and matching platform heels while her 17-year-old colleague sported an orange and black striped shirt, black jacket, and black pants.

Posing for pics on the red carpet, Pete Wentz wore a Metallica T-shirt as he joined his band Fall Out Boy before hitting the stage.

Unfortunately, Austin had a rough time during his travels, sharing his gripes on Twitter. "Having the worst flight ever!!! I'm sitting next to a crying baby... Then the mom stares at me... Then spilt her drink on me... The seats barley recline to 1inch........... And everytime I finally get to fall asleep the baby hits me!!!!!!!!! I JUST WANT SOME SLEEP!!! (And a new seat). While I was in the bathroom tweeting to you guys..... she stole my pillow.. #pillowless. Got 2 hours til I land, no pillow, no sleep, at least the baby is comfortable now and I have wifi."
