Oprah Winfrey had the time of her life at Beyoncé and JAY-Z’s On The Run II tour stop in Los Angeles over the weekend. On Monday, Gayle King, the media mogul’s best friend, shared several posts from the event including Winfrey throwing up the rapper’s signature diamond hand gesture.

During JAY-Z’s performance of the song “Public Service Announcement,” the Wrinkle In Time star bops along with her hands to the sky. “Diamonds up @Oprah!” King wrote under the video.

She also mentioned that it was Winfrey’s first time seeing the hip-hop couple in concert together. “Her FIRST time seeing Mr & Mrs Carter on stage together! Language dicey but @Oprah can hang.”
