The singer shared a post about enjoying “single life in a pandemic” on Instagram on Wednesday, after much speculation about her romance with the Hollywood star.
Jessie uploaded a video montage that showed her drinking wine and attempting to twerk, captioning it: “What my pupils are actually doing while I calmly stare at you trying to get a quick read on your energy... Single life in a pandemic is [crystal ball emoji].”
She added: “It’s supposed to be funny. So don’t get serious Sally in the comments. Sorry if your name is Sally and you aren’t serious.”
In January, Jessie and Channing revealed they were back together following a reported brief split, as they cosied up on Instagram.
He first appeared to confirm rumours they were dating in November 2018 when he praised her performance at London’s Royal Albert Hall, where he was in the audience.
It was thought they first started dating six months after Channing split from his wife of nearly nine years, actress Jenna Dewan.
Meanwhile, Jessie is one of the stars rumoured to be taking part in the upcoming series of I’m A Celebrity... Get Me Out Of Here!.
Other famous names rumoured for the ITV reality series include former Strictly Come Dancing professional AJ Pritchard, ex-footballer John Barnes and Coronation Street legend Beverly Callard.
