Terms between the estranged couple, who dated each other for eleven years, have turned sour as de la Rua has filed a lawsuit here accusing his ex-girlfriend of breaking a promise to continue paying him a share of her business profits, reported the Huffington Post.
The son of former Argentine President Fernando de la Rua argues that he left his career as a publicist while he was dating the star, eventually becoming her business manager and is thus entitled to monetary compensation for this work.
De la Rua is seeking 18 per cent of the profits from her deal with Live Nation, the world's largest entertainment company, a contract reported to be worth approximately USD 100 million.
The couple separated in August 2010 but did not go public with the split until last January, when the 35-year-old Colombian artist posted a letter on her blog citing the decision as "mutual".
