Ciara is claiming Future caused her to lose out on a potential half a million dollar endorsement deal by bad-mouthing her on social media and in interviews.

According to new legal documents obtained by TMZ, Ci Ci says an international cosmetics company who wanted to do business with her was scared away after Hendrix started trash talking the R&B singer over a disagreement in custody over their son. It was a potential $500,000 payout according to the Ciara.

The "Goodies" singer thinks Future's antics messed up her "positive reputation" and made her look, "controlling, dishonest, malicious, unreasonable, evil, conniving."

Future and Ciara's relationship has been tense, to say the least, since they broke up last year. As previously reported, the Atlanta rapper sounded off on his custody battle with Ciara back in January on Twitter typing, "I gotta go through lawyers to see babyfuture…the fuckery for 15k a month."

The singer later denied Future's claims and sued him for $15 million for libel. Things got even messier when Future counter-sued Ciara for legal fees claiming her career was over.

In mid-May, a judge in their custody battle ruled in Future’s favor, awarding joint custody to the feuding parents despite Ciara’s best efforts to portray Future as an absent father. Last month, Future ended up dropping his counter-suit.

Ciara has essentially moved on from the relation and recently married Seattle Seahawks quarterback Russel Wilson earlier this month to the displeasure of the Future Hive.
