Caitlyn Jenner is welcoming us into her world in an emotional new promo for her eagerly awaited E! docu-series I Am Cait.

"We're going to talk about everything," she says in the stunning clip. "We're going to do a lot of fun things for the first time. We're going to go shopping for the first time. Maybe even some boy stuff, like ride a motorcycle — because girls do that too."

Hell yeah they can, Cait!

The promo also sees Kylie Jenner cuddling up to her transgender dad, and Caitlyn explains the idea behind the series.

"Why did I decide to do a series?" she asks.

"I am telling my story. People don't understand looking into the mirror and nothing seems right, putting on clothes that you really don't identify with.

"This is about getting to be who you really are."

We'll raise a glass to that.
