It's big news, seeing how he and Jenna Dewan only recently divorced.
While it's never easy to see your ex move on with someone new, it's even more haunting when their new bae shares a striking similarity to you.
Many fans have pointed out that Jenna and Jessie look eerily similar, but Jenna has had the best response ever to those claims.
"FIRST OF ALL….whenever I hear of the 'striking resemblance' w/ Jessie J to Jenna Dewan ..my only thoughts are ummmmm no," a fan wrote on Jenna's Instagram.
"Just trying to spread positive vibes, keep doing you…to an absolute outsider from a small town you are doing it seemlessly."
Jenna responded, "positive vibes all the way."
Yes queen.
