The Price Tag singer shared a screenshot of a conversation between Step Up actor and her on Instagram DM on Monday Night.
The 30 years old singer drew a love heart around Tatum's message reading: "Yes I won't rest till I caress fresh face, Jess. I Will finesse 'til success. Never digress. Just progress. Bless".
Jessie and Tatum started dating in late October and Tatum never seem to stop admiring Jessie. The actor dropped a cheeky commented on the Instagram post of Jessie about the food and her makeup.
The pair were first rumoured to be together in September last year after Tatum's split with his ex-wife Jeena Dewan after nine years of marriage.
The estranged couple wrote: "We have lovingly chosen to separate as a couple. We fell deeply in love for so many years ago and had a pretty magical journey both together."
The then-pair further added: "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."
Proving to everyone that they aren't about hiding their relationship, the Magic Mike star supports Jessie J by attending most of her concerts including one with his daughter.
A source of People said to People: 'Channing is her biggest fan. He flies all over the U.S. to attend her concerts.'
Moreover, another source told to People: 'He works around the clock, loves being a dad and has a decent relationship with Jenna. Jessie J as well dedicated to her career and has a real-time sense of humor. She likes to have much of a good time. It is an exciting time for both of them to enjoy.”
On October 6, the pair were first spotted on a date at a mini-golf course.
