Making her first talk show appearance, Caitlyn Jenner chats to Ellen about why she didn’t always support same-sex marriage.

Ellen didn’t shy away from the hard questions when she sat down with Caitlyn Jenner last week. The talk show host grills Jenner on how being trans fits in with her conservative beliefs.

The former Olympian also talked about her marriage to Kris. She opened up about how she used to cross dress in order to feel like her true self and it was swept under the rug after her then-wife discovered what she was doing.

The full episode airs in the United States on September 8.
