LOS ANGELES, CA  [Friday May.4.2007]  /Mix103FM.com/ -- Rihanna got the surprise of a lifetime when producers of her new video brought Jay-Z in for a guest appearance.

Although the producer worked on her new album, "Good Girl Gone Bad," the young singer says she was still very
"starstruck."

Rihanna shared her recent experience with MTV: "They just said, 'We have a surprise for you.' I couldn't imagine it would be Jay-Z getting on the song. They played it for me, and I got goosebumps everywhere."

"I still can't believe that I'm shooting a video with Jay-Z and I have a song with Jay on it. It takes everything to another level for me in my career as far as experience goes."
