Selena Gomez Gets Grumpy At The Airport

But why? Seeing as she's back on with beau Justin Bieber, shouldn't she be in a better mood?

Over the weekend Selena Gomez was spotted flying back in to Los Angeles, and she covered up with a jacket and scowled at photogs as she walked back to her car.

Selena and Justin were in Salt Lake City, Utah for a mini-vacay with fellow famous couple Taylor Swift and Harry Styles, and the lovebirds were spotted smooching at the airport before boarding a plane to L.A.X. After Selena touched down, Justin tweeted, “All alone on the jet, missin u already :(.” Awww!
