I Am Cait trailer: Caitlyn Jenner 'still the same person'

The newest trailer for eight-part docuseries I Am Cait brings to mind Brody Jenner’s recent words about his father: “Caitlyn is just a much freer person. It’s incredible to see the difference between Caitlyn and Bruce.”

Indeed, the 30-second clip shows off a side of Caitlyn that is tangibly happier than she’d ever been on 10 seasons of Keeping Up with the Kardashians.

While Caitlyn admits that she has a lot to learn, however — for example, while playing tennis she suddenly realizes why women wear sports bras — she’s “still the same person.”

I Am Cait premieres July 26 at 8 p.m. ET on E!.
