Sources tell ET, Kelly Clarkson is facing unfair backlash over her Las Vegas concert, which she canceled just hours before the show. ‘The attention Kelly is getting feels unfair,’ one source says. ‘One of the best things about Kelly is, she’s a real person without a huge ego. She’s had a lot going on in her personal life, and is doing her best to balance it all with her duties at [her talk] show (which is on hiatus right now, so not a factor). She’s got to be a mom first, which a majority of the staff understands. She’s been through a lot in the last couple years, but shows up with a good attitude, ready to do her best.’
