Unless you’ve been living under a rock recently, you’ll know that people across the globe have been left shook at reports that Jessie J and Channing Tatum are dating.

Their rumoured relationship was only confirmed when the singer took to Instagram to share footage from Magic Mike Live – only for Channing to return the favour when he praised her for “pouring her heart out” during a performance at the Royal Albert Hall.

While Jenna Dewan has so far kept quiet about their relationship, she’s now reacted to claims that her ex-husband has picked a new girlfriend who looks exactly like she does.

A fan posted the following message beneath one of her Instagram posts: “FIRST OF ALL… whenever I hear of the 'striking resemblance' w/ Jessie J to Jenna Dewan. My only thoughts are, 'Ummmmm not even close…"

The fan added: "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 seamlessly."

Hinting that she agrees with the above statement, Jenna liked the comment and added: "Positive vibes all the way."

This comes as a source told E! that the 37-year-old “wasn’t surprised” when she heard they were dating: “Jenna knew that Channing was dating and it wasn't a surprise. A friend had told her what was going on."

Insiders have since claimed that both Channing and Jenna are focused on ensuring their relationship stays healthy for the sake of daughter, Everly: “They both plan to make her their very first priority."
