Jay-Z paused his concert in Oakland Saturday night to bring a two-time cancer survivor on stage.

That woman, whom ABC identified as Christina Cruz of San Jose, caught the eyes of the 48-year-old hip hop star with a glittery sign that read, "I beat cancer 2x 2 c u! I love u!!! Selfie or hug?"

"I gotta give you at least a hug," the 21-time Grammy winner said as he brought an ecstatic Cruz onto the Oracle Arena stage. A warm embrace and brief photo-op followed.

"Just know: You beat cancer twice, you can do anything," the rapper said. "Remember even in those dark times to smile. Always smile."

Cruz took to her Instagram after the concert to gush: "I can't believe he pulled me on stage and I got to hug him not once but twice," she wrote.

George Zimmerman threatened to feed Jay-Z to an alligator over the rapper's involvement in an upcoming Trayvon Martin documentary. Zimmerman gunned down 17-year-old Trayvon, who was unarmed, in Feb. 2012. Zimmerman claimed that producers Jay-Z and Michael Gesparro harassed his family for interviews and footage. "I know how to handle people who f*** with me. I have since February 2012.” George Zimmerman told The Blast “Anyone who f***s with my parents will be fed to an alligator."
