The gorgeous reality co-stars met up on Thursday night (3 November) and couldn't resist trying out the popular app.
They could pretty much pass as twins right?!
Kady and Emma had earlier been out with their Love Island other halves, Scott Thomas and Terry Walsh, enjoying dinner and then going on to the Couture Club A/W launch party. They ended the night at Kady and Scott's new home.
A photo posted to Emma's Instagram had the caption: "Double date heaven with these hunnies."
She also tried out a few Snapchat filters with boyfriend Terry!
Both couples have been going strong and blissfully happy since meeting on Love Island over the summer. Kady and Scott finished in third place, while Emma and Terry were placed fifth.
Since the show wrapped, Kady and Scott have moved in together in Cheshire, while Emma and Terry also live together and have adopted a ginger kitten named Boo.
Kady and Scott recently returned to TV for an appearance on Tricked: House of Horrors, which saw them baffled by various tricks pulled by magician Ben Hanlin.
