TOWIE hunk Mario, 27, posted a message about trust, suggesting that reports of his and Emma's break-up were definitely true.
He wrote: "Never trust anyone… Sometimes even those closest to you are the worst [sic]."
Model Emma was quick to respond, writing: "Trust?! Oh really, maybe I should let everyone know the truth…
"All you do is bring me down and put me down. This perfect boyfriend who continuously messages other girls. I'm finished [sic]."
Emma has since deleted her tweets – and she and Mario have yet to confirm the break-up.
The reports came as a shock to fans, after Mario admitted he wanted to move in with Emma.
He told OK! Magazine: "I'm buying a house this year, and that house is for me, but no doubt Emma will move in because she lives in Leeds, so it's pretty much all or nothing.
"That's the plan. My sister is getting married this year, so we will probably go to that together too."
Mario and Emma got together in November last year, and it's believed that they met in Miami.
