The 30-year-old model filed for divorce from the 'Black and Yellow' hitmaker yesterday (24.09.14) and friends say she had grown tired of his flimsy excuses for why she couldn't join him on the road.
Sources told TMZ Amber grew suspicious of the 27-year-old rapper - with who she has 19-month-old son Sebastian - when his tour began in July and he told her she couldn't come to the shows.
He reportedly told his spouse she should stay at home with their son, and the source says Amber also claimed Wiz repeatedly stressed he was their main bread winner and wanted to be left alone to make money.
However, the 'We Dem Boyz' hitmaker is said to believe Amber is making up the allegations to cover for her own closeness to newly-separated Nick Cannon, and has also complained privately that she is a ''big nag''.
Despite Wiz's suspicions, Nick - who is currently living apart from wife Mariah Carey - has insisted they are untrue and he and Amber have a strictly professional relationship, following her recent signing to his NCredible Entertainment management company.
The 'America's Got Talent' star, who has three-year-old twins Moroccan and Monroe with Mariah, 44, claims he only learned that Amber was having marriage troubles last week through her lawyers when he signed her on as a client.
The source added: ''That's when Nick says he found out her marriage was on the rocks and only then did the two share break-up stories.''
