Combs' lawyers dismiss the allegations. They claim that the cases are further examples of the lawyer representing those who claim to have been subjected to abuse seeking publicity.
One case concerns a boy who accuses Sean "Diddy" Combs of drugging and then subjecting him to sexual abuse in a hotel room in New York in 2005. The other case involves abuse of a teenager who was to participate in a reality series that Combs was producing in 2008.
In a statement via email to the AP news agency, Combs' lawyers write that they have the greatest confidence in the legal process and what the outcome will show.
"In court, the truth will prevail: that Mr. Combs has never assaulted anyone - man or woman, adult or minor - or engaged in sex trafficking", they write.
In previous allegations against the 54-year-old rapper and superstar, he is accused, among other things, of sexually assaulting women at parties and meetings over the course of two decades.
Combs has pleaded not guilty to charges of sex trafficking, abuse, extortion, and threats against several women, charges that became public the day after he was arrested and imprisoned in mid-September.
