Either Rob Kardashian and Blac Chyna are engaged, or the couple is toying with our already fragile emotions.

Chyna took to Instagram early Tuesday, April 5 to post a photo of Rob cheesing as she lovingly touches his face. That's sweet, but we've come expect moments like that from the lovebirds.

The big difference here is that Chyna is rocking a gigantic diamond ring on her left hand's ring finger and the caption says, "YES!.!.!"

There is only one way to interpret that, right? It's starting to look like the Kardashian family will soon welcome one more member.

Sources tell TMZ that Rob popped the question on Monday night and Blac Chyna said yes. To celebrate, the newly betrothed pair appear to have hit up a Los Angeles strip club with Blac Chyna's mom, Tokyo, who reportedly flew out to Los Angeles on Sunday to meet her daughter's boyfriend.

An insider told the site, "Tokyo thinks he's "the one" and is a way better match for her daughter than Tyga ever was. She loves Rob's positive attitude, kindness, good manners and sees he treats Chyna like a queen."

Jeweler Ben Baller, who counts Rob's brother-in-law- Kanye West among his clients, posted a close-up video of the stunning 7 carat ring on Instagram.

He included this caption: "Congrats to @RobKardashian & @BlacChyna on getting engaged. Rob, I have never seen you this happy before and I've known you since you were a teenager. I'm glad you came to your day 1 homie to get this massive [ring emoji] for your lady. You know I don't play when it comes to diamonds. God bless #7Carats #VVS #IFANDCO #BlacChyna #RobKardashian."

Rob and Chyna began dating in January of this year and have been inseparable ever since. The relationship appears to have done wonders for Rob. He's losing weight, smiling, connecting with his family and appearing in public again. After some initial reservations from the Kardashian/Jenner clan—mainly because Chyna is the mother of Tyga's son, King Cairo, and Tyga is Kylie Jenner's boyfriend—the family is reportedly warming up to the idea that this relationship is the real deal.

In fact, as we reported earlier, Kris Jenner is grateful to Chyna for helping her son find himself again. Kris is said to be particularly thankful to the 27-year old model for everything she's doing. "Kris is so grateful to Blac Chyna for rehabilitating her son," a source told Us Weekly.

Rob, 29, "went forever without any girl being interested in him," the source continued. "His confidence was shattered for so long, so to have this banging girl all over him has given him a new lease on life."

The happy couple tries to "have fun all day long." They workout together and Chyna cooks healthy meals for them to enjoy, which is why Rob has lost roughly 65 lbs. and counting.

Sounds like a match made in reality TV heaven. Congrats to the happy couple!
