Diddy to Students: Stay in School. Work Hard. Change Your Name Often.

When you want a roll model to speak to your students - and the Ghostbusters are busy - who you gonna call?

Diddy.

So figured the principal at Benjamin Franklin High School. He wanted a speaker who would get students' attention and certainly found it in this rap mogul turned soon-to-be-father-of-twins.

"This is a really important time for you all right now," Diddy said. "This is the time that is going to dictate your future."

The 36-year-old founder of Bad Boy Records looked the part in sunglasses and flashy jewelry. He called some students on stage and talked to them one on one about their goals. His advice: work hard and stay in school.

Evidently , Kevin Federline never received either of those memos.

"Take responsibility for your future. No excuses!" Diddy encouraged.

"We wanted someone whom they would sit down and listen to, someone who comes from the same type of background," said Principal Cristopher Johnson. "To have a superstar come in to talk is extremely powerful."

So are the abs on LL Cool J. We're just sayin.
