Channing Tatum and Jessie J are heating up. The pair took a big step in their relationship in early November — they became Instagram official.

Tatum, 38, gushed over his reported girlfriend in a post on Nov. 14, praising the singer for her recent performance in New Jersey.

"This woman just poured her heart out on stage at the Royal Albert Hall. Whoever was there got to witness something special. Wow," he captioned a photo of Jessie J as she sang in front of hundreds of fans.

Fans of the blossoming couple blushed at Tatum's remark, joking that the pair are now "insta official."
