Gomez was set to perform at the B96 Jingle Bash 2011 in Chicago on Saturday and at 106.1 KISS FM's Jingle Bell Bash in Seattle on Sunday, and the Seattle show has been postponed due to OneRepublic also pulling the plug on their performance.

Selena was reportedly at the Power 106's Cali Christmas 2011 concert in Los Angeles on Friday evening when she got word of the sad news, and she immediately left the show and headed home.

Gomez tweeted late last month that her mom and stepdad Brian Teefey were expecting their first child together, writing, "Momma and Brian are finally letting me share the news… My mommy’s carrying my baby brother or sister :) I’m the happiest girl in the world!”
