Lil Romeo is pissed at his mother after she sued him for fraud.

Reports say Sonya Miller has filed a lawsuit against her son's company all in a bid to get money from his father and her ex-husband, Master P.

Romeo's record company, No Limit Forever, was started in the '90s by Master P and Sonya and now, Sonya is fighting for a cut of profits from the company.

In her lawsuit, she claims her ex is using Romeo's similar company to hide millions as they battle in court over spousal support in their divorce filing.

However, Romeo insists that his own  'No Limit Records' company is more of his deal and less about his father and all the money in its bank account is his.
