This isn’t Tatum’s first time listening to her sing in front of a live audience.
Earlier this month, the star took his 5-year-old daughter Everly to see his girlfriend in concert at the Wiltern Theatre in Los Angeles.
News of their relationship broke in mid-October when an insider told PEOPLE, “It’s very new.”
Since then, the Magic Mike star has also supported Jessie J at her Houston concert in late October.
“Channing is her biggest fan,” a source said. “He flies all over the U.S. to attend her concerts.”
