Professor Green has hinted he's engaged to his girlfriend Fae Williams on Instagram.

The 33-year-old rap star took to the photo-sharing website late on Valentine's Day (14.02.17) to post an image of the model wearing an eye-catching ring on her engagement finger, prompting speculation the couple are set to tie the knot.

Pro - who was previously married to reality TV star Millie Mackintosh from 2013 until last year - captioned the photo: ''Fingers crossed this time ay (sic)''

However, the London-born star later confused matters by sharing a short video of Fae wearing the same ring on the index finger of her right hand.

And alongside a snap of himself wearing a ring on his little finger, he also joked: ''Engaged to myself. Wait a minute, wrong finger.''

Meanwhile, Pro previously admitted to feeling ''quite sad'' when his marriage to Millie broke down.

Asked what their split taught him, he said: ''I didn't get married to get divorced. Neither of us did.

''So all that really comes from it is it's quite sad that it ended.''

However, the rapper - whose real name is Stephen Manderson - also said he was feeling ''content'' with life and revealed he had taken positive lessons from his divorce.

The 'Read All About It' hitmaker previously said: ''I'm content and I'm just enjoying all of it.

''It feels pretty good putting music out again and the response has been amazing. I haven't just had a turbulent couple of years. My turbulence has been my entire life. But the end of my marriage has taught me there's no permanence in life.

''You have to accept that most things are temporary and there's a real positive to be drawn from that. These days I'm just happy.''
