There are plenty of reasons why Selena Gomez may have mailed in Sunday night's performance at RodeoHouston. Perhaps she didn't take the Daylight Saving Time change well. Perhaps as a North Texas native, she has an irrational dislike of Houston. Perhaps she was bummed about all the social-media rumors of Justin Bieber making an appearance at the rodeo, and how it was stealing the spotlight from her performance.
Whatever the reason, Gomez was just sort of there, going through the motions the way they've been rehearsed countless times. She sang, but she didn't seem to have any energy in her voice. She danced, but she never seemed to be interested in her moves. She was there, and that made people happy, even if it wasn't particularly memorable.
It was a show that could have really used a Bieber sighting.
