The Keeping Up With The Kardashians star accessorized with a bottle of Kendall’s 818 Tequila, a can of mixer and a 818 Tequila cap.

Sharing the steamy photos on Instagram, Kim praised herself for being such a good sibling.

She told her 235million followers: “Supportive Sister 818.”

Kendall, who announced the launch her alcohol line earlier this year, gave Kim’s post a like within an hour, along with 1.7million others.

Other fans showed their approval by posting both red heart and fire emojis.

In February, Kendall unveiled 818 Tequila and told her army of followers that her line had been four years in the making.

At the time, the 25-year-old model said: “For almost 4 years I’ve been on a journey to create the best tasting tequila.

“After dozens of blind taste tests, trips to our distillery, entering into world tasting competitions anonymously and WINNING… 3.5 years later I think we’ve done it!”

Kendall concluded: “This is all we’ve been drinking for the last year and I can’t wait for everyone else to get their hands on this to enjoy it as much as we do!”

A glitzy launch party followed in May and there was no expense spared, with the reality star treating VIPs to shots and drinking games at an exclusive venue.

However, Kendall has found herself coming under fire over the range several times.

The TV advert for 818 Tequila ended up trending on social media for the wrong reasons, after critics began accusing her of “cultural appropriation”.

In the commercial, Kendall could be seen walking through fields and holding a glass of her tequila while smiling and posing with a horse.

Workers in the field appeared as well.

One person wrote on social media: “Having workers in the fields while you’re on your horse looking down on them as if you own them. Disgusting and tone deaf.”

Another wrote: “Am I the only Mexican that thinks @KendallJenner’s acting hella colonizer with her new @818Tequila ad? Very very cultural appropriated vibes with that.”

Kendall has also been slammed by a rival tequila company and accused of ‘”copying” their brand.

Texas-based Tequila 512 bashed Kendall on Instagram with a striking image that showed a message from a confused customer inquiring about the parallels.

“Is that you or did someone copy you?” a buyer named Aaron asked 512.

The brand wrote on social media: “You may have seen that @kendalljenner released a ‘new’ tequila today.

“Note the similarities, including the color, the name and it is made at the same distillery in Tequila Mexico as ours.

“Their batches are being distilled twice. Ours three times. Yet she is charging twice as much per bottle.

“And here we are getting messages like the one in this post image. Doesn’t seem very cool. What do you think?”

512’s CEO Nick Matzorkis told The Sun they would NOT be taking legal action against 818 Tequila but demanded Kendall changed the label’s name.

Nick said: “Tequila 512 will not be taking legal action against Kendall Jenner or her tequila brand, nor are we looking for an apology.

“We are, however, calling on her to change the name of her tequila and/or change the labeling to create a clear distinction.”To date it appears Kendall has not met this request.
