The 38-year-old Magic Mike actor took to Instagram to gush about the British singer’s performance at the Royal Albert Hall in London on Tuesday, 13 November.
“This woman just poured her heart out on stage at the Royal Albert Hall,” Channing captioned his post. “Whoever was there got to witness something special. Wow.”
The American hunk also shared a short video of Jessie (30) on his Insta story, captioning it, “She went off tonight! #RoseTour.”
It’s also believed that Channing met Jessie’s mom, Rose Cornish, at the concert and sat seats away from her, Metro News reports.
But this isn’t the first time the Step Up actor has seen his rumoured girlfriend in concert.
Earlier this month, Channing took his daughter Everly (5) to see Jessie’s concert at the Wiltern Theatre in Los Angeles, People reports.
“Channing is her biggest fan,” a source said. “He flies all over the US to attend her concerts.”
Jessie J has also showed support for her new beau when attending Channing’s Magic Mike stage production on Saturday, 10 November, E! News reports.
“Magic Mike London opening night,” Jessie J captioned her photo on Instagram.
“Congratulations @channingtatum, what a show . . . Ladies and Gentlemen you don’t want to miss this.”
Channing, who separated from his wife Jenna Dewan Tatum in April, and Jessia were rumoured to be dating early in October after they were seen playing mini golf in Seattle, US.
