The holidays are all about bringing people together. And that’s exactly what happened when three of R&B’s biggest stars joined forces with artists outside their genre for some special holiday duets on Monday’s “Oprah.”

Alicia Keys and Tim McGraw covered John Lennon’s “Happy Xmas (War Is Over),” Mary J. Blige sang “What Child Is This” with Andrea Bocelli, and Jennifer Hudson dueted with Sugarland on “Silent Night.”
