Kendall Jenner was seen sipping the trendy drink of the day: an espresso martini.

But the Keeping Up With The Kardashians veteran offered a twist to the instant classic: her own tequila.

On Wednesday it was announced that her brand 818 Tequila and Chamberlain Coffee, Emma Chamberlain’s leading coffee lifestyle brand, have teamed up.

They were seen together in a kitchen as they tried to settle the espresso martini ‘debate.’

Jenner – who dressed in a chocolate brown crop top that displayed a hint of her toned tummy – insisted that the martini is best with tequila.

‘I’m so happy that 818 is collaborating with Chamberlain, Emma and I have been wanting our brands to do something fun together,’ said Kendall, Founder of 818 Tequila, told DailyMail.com in a statement.

Jenner added: ‘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.’

818 Tequila is an award-winning, hand-crafted tequila brand from the reality TV star and Vogue supermodel.

Produced using traditional methods in Jalisco, Mexico at a family-owned-and-operated distillery, the brand features four variations – a Blanco, Reposado, Añejo, and its ultra-premium Eight Reserve.

To create the best version of this score-settling cocktail, 818 Tequila and Chamberlain Coffee created limited-edition Candied Pecan Cold Brew Singles inspired by the flavors of 818 Tequila Reposado.

They are also debuting a limited-edition 818 espresso martini bundle on Chamberlain Coffee’s website.

‘Now, cocktail lovers don’t need an espresso maker: they can simply mix the candied pecan cold brew with the tequila for what is officially the cocktail’s most delicious rendition,’ a press release shared with DailyMail.com shared.

‘Starting today, fans can purchase the Espresso Martini Kit Bundle ($72) which features the cold brew singles, a cocktail shaker, and a martini glᴀss on Chamberlain Coffee’s website.

‘Consumers can also purchase bundle items individually, including the Chamberlain Coffee and 818 Candied Pecan cold brew singles ($16), cobranded cocktail shakers ($28), martini glᴀsses ($25), and limited-edition baby tees ($55). The Candied Pecan cold brew singles and 818 Tequila Reposado are also available for purchase on Gopuff in participating cities.’

‘Working with Kendall and 818 on this was such a blast,’ said Chamberlain Coffee Founder, Creative Director and Investor Emma Chamberlain.

‘The whole thing came together naturally because we adore each other and adore espresso martinis with tequila. We played around and ended up creating a unique take on an espresso martini that we know people will love.

‘The Chamberlain Coffee Candied Pecan Cold Brew Singles with the 818 Tequila Reposado flavors is nutty and sweet and perfect. I am so excited for people to try it.’
