Just 10 weeks after they took their relationship public, Rob Kardashian popped the question to his new flame on Monday night.
โThey are engaged. They have been up all night celebrating,โ a source close to the duo confirmed to People. โRob is very excited.โ

It looks like Blac is very happy with that sparkler! The couple shared this photo on their social media accounts to confirm the exciting news.
Following the confirmation, the curvy 27-year-old took to Instagram to announce her big news, simply saying, โYESโฆ!โฆ!โฆ!โ
Blac accompanied the caption by taking a selfie with her future spouse, where the mum-of-one showed off the large rock on her wedding finger.
Rob enlisted LAโs jeweler to the stars, Ben Baller, to craft the exquisite new creation.
The engagement ring features a 7-carat center stone with VS1 clarity, which is set on a delicate VVS diamond eternity band.
Clearly proud of his magical creation, Ben shared a video of it on Instagram.
โCongrats to @RobKardashian & @BlacChyna on getting engaged. Rob, I have never seen you this happy before and Iโve known you since you were a teenager. Iโm glad you came to your day 1 homie to get this massive for your lady. You know I donโt play when it comes to diamonds. God bless,โ he penned.
And Blac was clearly a happy gal, quipping, โIโm so blessed and honored to have good man in my life, I love you @robkardashian ! #7carats #VVS @benballer.โ
The 29-year-old took his future wife and her mum, Tokyo, to celebrate at Ace of Diamonds strip club in Los Angeles.
Rob proudly shared a snap of Blac holding a wad of dollar bills, proudly flashing her new bling.
One of the first people to publically congratulate the pair was Blacโs bestie, Amber Rose.
โCongratulations to my Family @blacchyna and @robkardashian!!!โ she gushed on Instagram.
โ[Please] donโt let nothing or no one tear u guys apart! I never seen my sis so happy and I couldnโt be more happy for her! Sometimes we find love in the strangest places. Lol God Bless you 2! Now letโs get this wedding together so yโall can start making some babies #TrueLove #putaringonitsouknowitsreal #BlacRob.โ

Even the mini Kardashians, North and Penelope, are on this trip!
Interestingly, though, none of the family members were in Los Angeles when Rob popped the question.
Kris whisked away all of her daughters, as well as Kourtney Kardashianโs ex Scott Disick, Kim Kardashian Westโs husband Kanye West, and Kylieโs boyfriend Tyga on Monday afternoon for a surprise trip to Colorado.
โSo, we are on our secret journey โ we donโt know where weโre going because Kris Jenner wonโt tell us โ but, as long as the sisters are together, weโre OK,โ Khloe, 31, joked on Kylieโs Snapchat.
So far, none of the usually social media savvy reality stars have publicly congratulated their brother Rob.
Of course, things will no doubt be a tad awkward at Christmas and family gatherings considering Robโs younger sister Kylie Jenner is dating Blac Chynaโs ex, Tyga, with whom they share son King Cairo Stevenson, three.
One thing is certain, the Kardashian clan will certainly have trouble keeping up with this news!

Rob admitted to putting on over 45kg over the past few years.

But thanks to Blac, she has helped transform his life.
