Rob Kardashian and Blac Chyna are finally opening up about their much talked-about romance.

Days after the release of the explosive first promo for their new reality show, Rob & Chyna, the couple sat down for a Facebook Live interview, where they dished on their upcoming wedding, Chyna's pregnancy, whether or not they'll keep the Kardashian tradition alive with a "K" name for their baby.

"If it was up to Rob, literally, we would go tomorrow," Chyna announced, in response to a fan's question about when they'll get married.

"We would have been at the courthouse, downtown, a long, long time ago," Kardashian agreed.

"He wants to go there, but I'm like, 'We need to do it the traditional way,'" said Chyna, who was never married to ex Tyga.

"'Cause I wanna turn up after! I wanna turn up on my honeymoon and I wanna turn up on you," she explained. "But I think next year to kind of give you guys an idea. It's not going to be this year. I kind of want to get my body back."

The couple's new baby was big topic during the Facebook Live event, with many fans curious to know if the pair will continue the Kardashian tradition with a "K" name for their little one.

Rob noted that Chyna's 3-year-old son, King (who will be featured on the couple’s reality show) already bares the "K"initial, but the pair said they're not too sure they'll stay with the tradition.

"You guys have to stay tuned for that too 'cause I'm not trying to give up no more details about the baby," Chyna coyly answered, while Kardashian offered a "probably not."

Whether or not their baby will be given a signature "K" name, he or she is sure to be surrounded by a lot of "Ks."

Not only will Kardashian's sisters be featured on the show -- "Of course, they’re my family. They're my only friends," he explained -- they'll also be babysitting.

"I'd probably let Kylie babysit," the former Keeping Up With the Kardashians star replied to a fan question about whether Kendall or Kylie would make a better babysitter.

Chyna, who was involved in a brief feud with the 19-year-old lip kit creator earlier this year, couldn't agree more. "Yeah, she can babysit the baby and King at the same time!" she offered.

While Kylie's help is welcomed by the newly engaged couple, Kardashian and Chyna also dished on which member of their famous family gives the most unsolicited parenting advice.
