Channing Tatum, Jessie J are going public: A timeline of their blossoming relationship

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."

"FIRST OF ALL ☝🏼....whenever I hear of the “striking resemblance” w/ Jessie J to Jenna Dewan ..my only thoughts are ummmmm no 😂 not even close,” the fan wrote. “And I don’t have a horse in the race but gf you are untouchable. Just trying to spread positive vibes, keep doing you...to an absolute outsider from a small town you are doing it seemlessly ❤️," one Instagram user wrote.

"Me too! It’s an absolute insult to Jenna’s beauty - inside and out!” they said. “He’ll never find another Jenna; she a once in a lifetime kind of woman ❤️," another added.
