The Magic Mike actor has been seeing the 30-year-old singer each other for a few months, according to US Weekly.
Tatum, 38, who split from the Step Up actress in April, has been spotted at Jessie's concerts in Seattle and Salt Lake City.
And last week the two were spotted at a mini golf course, according to reports on social media.
One user said: “Lol they were hella nice. Jessie came down and I was shook and then when I went to get them to play, Channing turned around and I was like ?.
"We hugged and got a pic and then I got to hear Jessie singing somebody to love with the radio at the end of the course.”
An insider told People on Tuesday that their relationship is "new, casual and they're having fun together."
Jessie, who hails from London, is currently on her world tour R.O.S.E. after releasing her album of the same title in May.
Tatum and Dewan were together for nearly 10 years and have a five-year-old daughter named Everly.
Announcing their split on Instagram, they said: "We have lovingly chosen to separate as a couple.
"We fell deeply in love so many years ago and have had a magical journey together.
"Absolutely nothing has changed about how much we love one another, but love is a beautiful adventure that is taking us on different paths for now."
The Price Tag singer presented Tatum with the Best Comedic Performance at the MTV Movie Awards in 2015.
Reps for both Tatum and Jessie J have not responded to request for comment.
