Reclusive pop superstar Prince gave his latest protege TAMAR a boost on Tuesday night (24JAN06) when he joined her onstage at Los Angeles club the Roxy.

The sultry singer was playing a showcase concert at the Sunset Strip venue when Prince stepped up to play guitar with her on the song EVERY STEP OF MY HEART.

And the PURPLE RAIN star was in the mood to sing too - he grabbed the microphone and belted out a rendition of his PARTY MAN hit to celebrity fans like Queen Latifah, Elijah Wood and tennis ace Serena Williams, who were at the Roxy to check out Prince's latest star.
