It looks like Rob Karadashian has faith he and Blac Chyna are in it for the long haul.

Need evidence? Check out his neck. In a series of Snapchat posts, Rob's pregnant fiancee captured video of the new tattoo Rob apparently got in honor of his new life and romance.

The tat reportedly says either "Anjila," Chyna's real name, in Arabic, or Aniyla, the rumored name of the couple's baby-to-be. (Said rumor, however, should be taken with a massive grain of salt given that the not-so-reliable website Media Takeout seems to have been the first to report it.)

With "Rob and Chyna" slated to premiere on E! Sept. 11, the pair have made numerous headlines in recent weeks, focused on their baby and wedding plans.

During a Facebook Live chat Aug. 17, they revealed they'd like to have three more kids after Chyna gives birth to their first. They also opened up about their trip down the aisle, which Chyna said would likely take place next year, although Rob would rather say "I do" sooner with a courthouse wedding.

As for the delay, Chyna said she wants to wait until she gets her figure back after the baby arrives. She's also hoping a 2017 wedding will give her a chance to have a little more fun than a wedding during her pregnancy might.

Rumors that Rob and Chyna were dating started in earnest in January after she posted a pic of what seemed to be his arm draped around her. Initially, the relationship was a coup in the Kardashian/Jenner household, despite Chyna's previous friendship with Kim Kardashian West.

Prior to getting involved with Rob, Chyna dated Tyga, with whom she shares a son, King Cairo. When Kylie Jenner started dating Tyga, Chyna expressed her disapproval on the radio, saying at one point, "[Tyga] should be ashamed of himself" because "he has a beautiful woman and a baby, and left that for a 16-year-old who just turned 17."

Kim and Kylie, along with Khloe Kardashian and Kendall Jenner, didn't take such declarations well and complained about Chyna's relationship with Rob.

They seem to have made up since then, with the whole family, including Kris Jenner, voicing approval of Chyna and support for Rob's happiness.
