This ain't no joke! We got the proof!

Right after Rob Kardashian asked his girlfriend of two months, Blac Chyna, to be his wife last night, the class act and his betrothed high-tailed it to Ace of Diamonds strip club to celebrate. What a lovely night!

We saw the Snapchats and tweets that the pair posted last night but now we have video of the post-engagement celebration! OMG! THIS IS REAL!

In the video, the usually clingy couple are seen barely noticing each other until an announcer comes on the PA and congratulates the gruesome twosome, prompting Chyna to show off her bling ring.

That's right -- Rob gave his lady love a $325K seven carat round brilliant cut diamond in a VS1 clarity with a VVS diamond eternity band setting by celeb jeweler Ben Baller. We have a feeling Kylie and Kris Jenner are DYING right now!

In addition to the strip club stop, the former stripper posted a photo of her bauble and her new fiance with the caption, "YES!" Close pal Amber Rose appeared to confirm the big news with a tweet. "Congratulations to my Family @blacchyna and @robkardashian!!! 💍💍💍😍😍😍😍😍," she wrote later in the evening.

THIS IS REAL LOVE, Y'ALL!

An engagement should be a momentous occasion, but we have a feeling that the whole Kardashian may have some reservations. The fam has been none too pleased about the romance from the get-go, so it remains to be seen how this news will land.

Kris, Kim, Kylie, and the rest of the girls have yet to respond to the engagement on social media, but we have a feeling the well wishes aren't exactly going to be pouring in. How awkward is this for Kylie and Tyga? Now the rapper's son's stepdad is going to be his girlfriend's brother!
