Jessie J speaks out on comparisons to Channing Tatum's former wife Jenna Dewan

Jessie J is unhappy with the comparisons being made online of her to current boyfriend Channing Tatum's former wife Jenna Dewan. The 30-year-old singer shared a message on Instagram insisting that women should support each other, instead of comparing themselves.

The Alive singer wrote in a lengthy post: "I rarely, but sometimes see that my name is involved in stories online that I do not agree to. I often ignore them as 99% of the time it is something that doesn't serve any positivity to speak on."

"However there is a story I have seen be re written over and over again in the past few weeks that talks about myself being compared directly to another beautiful woman regarding our looks and people picking who they think is prettier," she added.

She continued: "I have continuously tried to find something positive from this article...I am yet to...I'm talking in general too. Beyond this story. It's constant with women. Picking favourites."

"I am so disappointed and embarrassed that my name is even involved. It's not something I stand for, at all. I don't take stories like this lightly. Because I know the kind of impact it has on younger girls reading it. I spent so much of my childhood trying to be comfortable in my skin just like so many other little girls, and when I got older, decided to spend my career making lots of music to try and help/inspire myself and all the other women to see their beauty from inside out and will continue to do so," Jessie shared.

Adding on, Dewan did not hold herself back and praised her on Twitter. She said: "Amen Jessie! Yes!!!! Women for women all the way. No need for negativity. Let's live in a world where we support each other and raise each other up. Like I said before, positive vibes all the way. Nothing but respect."

Tatum and Dewan tied the knot on July 11, 2009, after meeting each other for the first time on the set of their movie, Step Up in 2005. They announced their split on April 2, through a joint statement on social media accounts.
