*A lawsuit has been filed against pop star Rihanna by her former personal trainer, who accuses the singer of owing her $26,144 for services in 2009.

According to the claim filed last week at Los Angeles County Superior Court, Cindy Percival says she’s owed the unpaid wages for services rendered between September and October.

Percival alleges that she was contracted to work with the star for “exclusive personal training services” at a cost of $1,500 a day.

She is also believed to be demanding $2,644 in travel expenses, having accompanied the 22-year-old throughout Europe.
