It looks like someone had an awfully good time at the gym!!
We're guessing the multi-talented actress witnessed some pretty silly shenanigans at the gym, because she couldn't help but flash her amazing smile as she headed home for the day!
That, or her friend just told her a really funny joke!
All we know is we'd probably be grinning ear-to-ear too if we managed to look THAT good in sweaty gym clothes!!
