The privileged reality TV personality wrote: "That Rylan guy winning anything epitomises British demise..... @spencerpratt all the way."
But Rylan clearly thinks a strong attack is the best form of defence, because he hit back at Spence on two fronts.
He tweeted: "@SpencerGeorgeM how about you drop yourself out and run back to your parents bank account, or better still find a fake girlfriend..."
The "fake girlfriend" comment was a reference to Spencer's unfortunate relationship with Khloe Evans - the winner of The Bachleor - who didn't want anything to do with him afterwards.
And there was an unlikely peacemaker in the form of Spencer Pratt, who interjected to say: "@SpencerGeorgeM @RylanClark - It's a moot point, as @CharlieSheen already won everything on Earth #winning."
Rylan's put-down appears to have done the job, as Spence has kept schtum since.
