Puppy Loving Ashley Tisdale Should Be Smiling, But…

Fresh off her flower-power High School Musical promotional tour in Rome, a jet-lagged Ashley Tisdale clutched her dog Maui and stumbled through LAX to her car.

The Tizz looks less-than-thrilled here, unlike other times she’s flown through LAX with her pooch.

What’s with this chick? Can’t she crack a smile anymore? You’ve got the #1 movie in America, Tizfrown. Roll with it, girlfriend.

Of course, all that hard work and promotion doesn’t come without its price. The 23-year-old cougar hasn’t been photographed with boyfriend Jared Murillo, 19, in weeks.

Could the halting of those happy times be the reason for Ashley’s dour expression lately?
