Kendall Jenner's award-winning tequila brand 818 Tequila and Emma Chamberlain's coffee lifestyle brand Chamberlain Coffee have joined forces to launch a limited edition espresso martini kit.

Jenner commented 'I'm so happy that 818 is collaborating with Chamberlain. Emma and I have been wanting our brands to do something fun together. We're not only creating something delicious together - we're settling the debate, once and for all, that espresso martinis taste best when they're made with tequila'.
