There were rumours the couple – who announced they were together last summer – had called it quits in May after they removed pictures of each other from social media.
But Sanchez reacted angrily to reports, tweeting: “Why is there so much evil and envy in these people?

“I wish you happy and that there is not so much evil in your hearts. KARMA do not bother my partner RESPECT”.
