Let's be honest -- no one's keeping up with the Kardashians these days because it's ALL about Bruce Jenner.

E! has released a minute-long promo for the upcoming special Keeping Up With the Kardashians: About Bruce, and we hear a few audio snippets of a very emotional Kylie and Kendall Jenner playing over archive footage of Bruce playing with them as kids.

"You think someday you're going to get over it," Bruce says. "These are my secrets that I have to deal with on my own." Kris Jenner talks about how she first met Bruce, and Kim and Kourtney weigh in on his transition as well. You can hear Kylie say, "I do want to meet her, when he’s ready, when we’re both ready," but it's Kendall who breaks down. "I just don’t like when people say, 'Bruce is gonna be gone,'" she says through tears. Bruce comforts her and says, "I'm not going anywhere."

Bruce adds, "I don’t think I’ve ever been as scared in my life as I was to be extraordinarily honest with my kids."

The special airs on May 17 and May 18 at 9pm on E! ... We'll definitely be watching!
