Is Professor Green engaged after THIS Instagram post?

Professor Green has sent fans into a frenzy posting this picture of his girlfriend Fae Williams wearing this HUGE diamond ring!

Fae is wearing the ring on her wedding finger and Pro. Green captioned the picture: "Finger's crossed this time, ay." Damn that's some SERIOUS shade at first wife former Made In Chelsea star Millie Mackintosh.

But then just as we were heading to buy a new wedding hat, Pro. Green then started posting other pictures with the ring on Fae's other hand and even on his own!

Guess we'll just have to wait and see!
