Caitlyn Jenner -- No Hiding This Smile

EXCLUSIVE

Caitlyn Jenner is doing something Bruce Jenner rarely did ... smile.

Caitlyn was out at the Four Seasons in Westlake Village with some of her girlfriends and she was grinning almost the entire time, as she strolled through the hotel's Japanese garden with Jeni and Didi.

Hard to believe it's been less than two months since the unveiling.
