Opening arguments in the long-delayed R.Kelly case are finally set to begin today.

Up for central debate is whether or not the Grammy-winning singer is even the man in the alleged sex tape featuring an underaged girl.

Kelly's lawyers maintain the singer is not the man in question in the production. Meanwhile, prosecutors are out to erase any tinge of reasonable doubt about who was on that tape and what took place.

At the heart of the case is the now 23-year-old woman that prosecutors say was the girl in the tape. The woman denies she's the girl on the tape and the defense also contends, whoever the girl was, may not have been a minor at all.

Jury selection was completed last week for the trial; the jury consists of 12 jurors, eight of whom who are white and four who are black. Among the jury are a young woman who said she was raped before, a businessman who said he believed Kelly to be guilty, and a Baptist preacher's wife.

Kelly, who has pleaded not guilty, could face up to 15 years in prison if convicted. -Jayson Rodriguez
