On Wednesday night, Jessie was spotted riding on the back of a motorcycle with Channing in Los Angeles, California. The Magic Mike star was also seen outside of the British pop star's home that same day.
While it may appear that these two are back together, a source tells ET that Channing and Jessie are just friends right now, nothing more.
"Happy 40th birthday to this special man right here," the "Domino" singer wrote, alongside a photo of Channing standing waist-deep in crystal clear ocean water. "You are truly one of a kind. I am so grateful you were born, and even more grateful that we met."
Another post was a short clip of the actor in swim trunks and a tank top -- shot with a retro, film-grain filter -- as he jumped from a platform into the ocean at an unidentified tropical resort.
"Keep living your BEST life," Jessie wrote over the video.
Earlier this month, a source told ET that Jessie and Channing's breakup was amicable, noting that the couple tried to make it work, but in the end, they realized they were better off as friends and it was time to move on.
