The party continued as viewers got a behind-the-scenes look at Oprah’s star-studded 50th birthday weekend.

One of the celebrations—a ladies luncheon—included a surprise performance by Celine!

Dressed in green, Oprah's favorite color, the Grammy® award-winning superstar performed "Because You Loved Me" to help the guests—50 fabulous women—celebrate Oprah's 50 years of life. The Canadian singer also sang "Happy Birthday" to commemorate this milestone.
