Proving she's all about the girl power, Jesy was quick to jump to the defence of her former bandmate and couldn't resist making a sly, but sassy, dig at former 1D star Zayn while performing on stage.
Y'know just so we could all see her do it...
While performing Little Mix's number one hit Black Magic, Jesy made sure to point at Perrie when Jade Thirlwall sang: "... just to help him see what he's been missing."
And it was clearly obvious what Jesy (who is now engaged to boyfriend Jake Roche) was getting at, as the crowd of fans started screaming and Perrie, clearly seeing the amusing side, couldn't help grinning before poking her tongue out at her bestie.
She's got your back.
On seeing the video, fans of the girlband were quick to comment. One user wrote: "I love that Jesy threw shadeee at Zayn... #girlpower." While another said: "If I was Zayn I would be pretty careful and watch my step because Jesy. Just Jesy."
It's not the first time one of the Little Mix girls has stepped into defend Perrie. Shortly after her break up, Perrie was asked in an interview how she was doing, with Leigh-Anne Pinnock quickly jumping in and shutting down any questions related to Zayn.
"We don't really want to talk about it," she told the interviewer.
Jade, meanwhile, wasn't afraid to show what she now thinks of Zayn and was spotted holding onto a sign that read: "Zayn is irrelevant anyway." Ouch.
News of Perrie and Zayn's split first broke nearly two weeks ago, with the Little Mix star said to be "devastated".
It was reported Zayn decided to end their four year romance by text message, calling off their engagement. And his decision to call it quits came as a surprise to Perrie, who reportedly thought their relationship was "the best it had ever been."
Following the break up, Perrie has been in America on a promotional tour with Little Mix and could be opening up about her and Zayn's split on The Late Late Show. According to The Mirror, host James Corden will ask Perrie about her broken engagement.
Little Mix are set to be guests on the chat show on 18 August and ahead of their appearance, Perrie has been showing her ex-beau what he's been missing herself with a series of bikini selfies.
After all, nothing says 'look at what you've lost' like a sultry snap...
