WATCH: Kim Kardashian breaks silence on stepdad Bruce Jenner's changing appearance

It's Bruce Jenner's story, and he'll tell it if and when he wants to.

That's what Kim Kardashian has to say about the ongoing speculation over her 65-year-old stepfather's changing appearance. She addressed the rumours today during an Entertainment Tonight interview.

Check out her comments in the video above.

This is the first time Kim has publicly spoken about the subject, and what she says — or rather, doesn't say — sounds like a confirmation that something's definitely up with Bruce.

After InTouch magazine ran an article featuring a Photoshopped cover pic of Bruce wearing make-up and women's clothing with the headline "Bruce's Story: My Life as a Woman", the family rallied behind him. Last week, the Kardashian-Jenner daughters posted a pic with him on Instagram with the caption "Family First".

During the ET chat, Kim, 34, also discussed her baby plans with hubby Kanye West (yes, they're trying) and insisted that she's not already pregnant.
