Cheers to Caitlyn Jenner! The former Olympic champion is living life to the fullest with her close friends and family. In the latest I Am Cait promo, Jenner gets more comfortable with her new self, changes up her hairstyles, and, oh yes, realizes the one item female athletes need most.

"I have a lot to learn," Jenner, 65, says in the new clip. "Now I know why girls need a sports bra!"

The Keeping Up With the Kardashians star embraces change in her upcoming E! series, and spends time with good pals. She also wears a short skirt while playing tennis, has a heart-to-heart with her mother, Esther Jenner, and rummages through her glam closet with Kim Kardashian.

Fun tidbit: She has the same dress as ex-wife Kris Jenner!

"Hang out with the people who love you," Jenner says in a voiceover. She tells Esther: "I'm still the same person."
