Whether you're totally shocked or saw it coming a mile off, the news that Rob Kardashian is set to tie the knot with Blac Chyna has rocked social media today.

And with thousands taking the chance to slam the reality stars' upcoming nuptials, at least Blac Chyna knows she'll always have the backing of her BFF Amber Rose.

Taking to Instagram to share the same image which Chyna uploaded earlier today, Kanye's ex wrote: "Congratulations to my Family @blacchyna and @robkardasian!!"

"Please don't let nothing or no one tear you guys apart!" she wrote in a post which has clocked up 68,000 likes in less than an hour.

"I never seen my sis so happy and I couldn't be more happy for her!  Sometimes we find love in the strangest places," she wrote in the tribute to the newly-engaged couple.

Already excited at the prospect of becoming an honorary aunt, 32-year-old Amber finished the post, writing: "God Bless you 2! Now let's get this wedding together so y'all can start making some babies."

While Amber may be over the moon for the loved-up couple, the same can't said for everyone online today, with thousands doubting the validity of the relationship.

"Shut the f**k up!!! No way. She wants him for his monayyyyy" wrote one Instagram user while another huffed: "Oh ffs you gotta be kidding me."

We can't WAIT to hear what everyone's favourite momager has to say about this one.
