*Look out Sheila E.  With drumsticks in hand, Rihanna is looking to expand her profession beyond just singing.

Rock drummer Travis Barker has been giving the singer private music lessons, according to a posting on his Twitter page – and she’s a great student, he says.

“Teaching Rihanna some things on drums,” the blink-182 drummer tweeted on Tuesday, along with a photo of the pair at a rehearsal space in L.A. “She JAMS!!!!! Watch out for her!!”

Rihanna can be seen behind a drum kit in the video for her latest single “Rude Boy,” which currently sits atop Billboard’s Hot 100 for a second straight week.

A source tells People.com that she really wanted professional tutoring from someone like Barker to so that she can perform live on her upcoming European and U.K. tour.
