Amelle, 31, broke the news of their marriage last year on Twitter, revealing they’d said ‘I Do’ in the romantic location of Mauritius, but a series of spats have allegedly pushed the former Sugababes’ singer to the limit.
A source told The Sun: “It’s been a difficult few months for them and the marriage is on its last legs.
“Amelle is struggling to recognise Marcio as the same man she married. The honeymoon period is definitely over and he is spending a lot of time away from the family home.”
The insider added: “During a recent heated row Amelle told him she wanted a divorce, but as yet they haven’t filed legal proceedings.”
Amelle sparked rumours of trouble in paradise earlier this month when she changed all of her social media handles back to her maiden name.
She also showed off a dramatic transformation, revealing she’s dyed her brunette locks platinum blonde.
In October last year Amelle revealed she and Marcio had married just six days after he popped the question.
Sharing snaps of their wedding rings – which have since been deleted – she gushed: “Mr and Mrs Sousa Rosa.”
Amelle has yet to comment on the reports of their split.
