Wilson can be seen posing in front of a PP2 graffiti mural in the photo with co-stars Elizabeth Banks, Brittany Snow, Ester Dean, Kelley Jakle, Alexis Knapp and Hanna Mae Lee.

The funny woman - who plays Fat Amy in the movie - accompanied the pic with the caption: "1st day of PP2 rehearsals!"

While Wilson and Co can be seen in the snap, Anna Kendrick, Anna Camp and Skylar Astin are noticeably missing.

Pitch Perfect 2 is due to hit cinemas on May 15 2015. We can't wait…
