The 37-year-old performer uploaded a snap of his wife-to-be Karima, 36, modeling her stunning engagement ring and with the sweetest caption.
The songwriter wrote: ‘You call me easy love. I call you my gorgeous thing. Loving me isn’t always easy, but you are always gorgeous.’
Karima also posted a snap of them kissing and typed: ‘02.10.21 said Yes.’
The rapper, whose real name is Stephen Manderson and Karima, welcomed their first child, Slimane Ray Manderson, in March this year.
Sharing an insight into their journey to parenthood, he said: ‘Privately we’ve endured what so many parents-to-be have, your journey to us wasn’t a straight line whatsoever, it was a rollercoaster right up to your arrival.
Praising his partner, the musician added: ‘As mum’s go, you’ve lucked out; you have the best example of what a brave, strong, passionate, loving, kind and both considered and considerate woman is.
‘One day I’ll tell you about how amazing she’s been throughout this whole process/ordeal and all the things she’s soldiered on through, with all of the optimism required to see this through.
‘All I’ve been able to do for Mama is be supportive, which despite my very best efforts still left me feeling a bit redundant at times and for good reason; I was! I couldn’t for a second take on even a part of what she was going through physically, which was a lot.’
Pro Green was previously married to former Made In Chelsea star Millie Mackintosh.
The couple finalized their divorce in May 2016, the same week that Millie went public with Hugo Taylor, her former Made In Chelsea co-star boyfriend.
Pro Green previously admitted his divorce hasn’t put him off getting married again. He said in an interview with Closer magazine in March 2018: ‘I’d love to be a dad one day, but I’m not broody yet – I can have them until I’m 50
