Ouch! Professor Green is fuming over THAT snap of Millie and Hugo

Break-ups are never easy, but when they're played out in the glare of the media spotlight there's no doubt that they're one hundred times harder as rapper, Professor Green, is currently discovering.

Having parted ways from his wife of two-and-a-half years, Millie Mackintosh, back in February, it looks like the Just Be Good To Green singer is struggling to come to terms with the fact that she is clearly moving on.

With the former Made in Chelsea star seemingly back on with ex-boyfriend, Hugo Taylor, Millie has wasted no time sharing snaps of their re-blossoming romance on social media, and her ex-husband is not happy.

Having lived it up with Hugo at the Grand Prix this weekend, Millie finished her round-up of snaps with a photo that shows the pair getting their smooch on, writing: "What a perfect end to an amazing weekend."

Appearing to respond to the photo moments after the snap was uploaded, Millie's ex-husband pointedly tweeted: "Money really can't buy you class, can it?"

Money really can’t buy you class can it

The singer was inundated with messages of support following his tweet, with fans flooding his page to offer words of advice.

"You don't know me, but from what I've seen of you, you're better than that, easier said than done, but rise above it," wrote one fan while another tweeted: "No, but your health is your wealth as my Dad always says. Your real love will come, one that deserves you, chin up."

Sad times.
