She did date De la Rua for over 10 years, but that doesn't mean that he helped her get where she is today in her career. Shakira says that yes he did advise her, but that was it. He was not what made her who she is today and doesn't deserve any money at all. She is trying to get the lawsuit to just be dropped completely.
News came out a while back that he was planning to sue her for $100 million, but now it is a lot higher and sounds like he has decided he is worth more than he originally thought. Shakira thinks his help is not worth one penny at all.
It is still unknown if the $250M lawsuit against Shakira will be dropped. She doesn't even want it to go to court.
