Girls' Generation's Jessica and f(x)'s Krystal were spotted on a sisterly date in Los Angeles as the two will be taking part in a global event for luxury brand, Jimmy Choo, on April 15.

Jessica uploaded the pictures onto her Weibo on April 14 along with, "The green grass is so lovely.  Always love being in LA ."

The two appear to be at a grassy park, enjoying the beautiful weather and warm sun in the city.  In one picture, Jessica smiles brightly into the camera as Krystal stands in the background with windswept hair, striking a humorous pose.
