A new teaser trailer for Caitlyn Jenner’s upcoming docuseries, “I Am Cait” has been released, showing the former Olympian looking happier than ever.

In the 30-second clip, Jenner is noticeably beaming, as she toasts with her friends, plays tennis and gets fashion advice from stepdaughter Kim Kardashian (who steers Caitlyn away from a dress her mom, Kris Jenner, also has). The 65-year-old admits she has a lot to learn, but notes that she’s “still the same person.”

The trailer was posted on the “I Am Cait” Twitter page Wednesday morning. You can watch the whole thing below:
