Jennifer Lopez had a look of frustration on her face when she found herself locked out of the Tracy Anderson Studio in California on Wednesday.

A Backgrid.com photographer caught the 53-year-old pop star sprinting to the front door of the studio. But when she got to the door, it was locked.

Jennifer knocked again and again, but no one came to the door. The make-up free singer/actress was dressed in a canary yellow crop top and snakeskin leggings.

She ducked into a corner and tried to hide her face from the photographer while she waited for someone to let her in.

Jennifer knocked repeatedly but no one came to the door. She looked anxious as the minutes ticked by. Wealthy stars like J-Lo aren’t accustomed to waiting outside like normal folk.

After her rigorous workout, Jennifer was seen leaving the gym and getting into a waiting Uber.

You can bet someone got fired for making Jennifer wait outside for 5 minutes.
