The eldest of the Keeping Up With The Kardashians sisters sizzled at the brand's photocall on Wednesday evening (8 June), showing just why she's been tapped as the new celebrity face of the products.
Kourtney, 37, teamed black high waisted trousers with a striped bralet and choker - so hot!
The reality star was named the brand ambassador for Manuka Doctor in April, saying at the time: "I have been using the Manuka Doctor honey line for many years so when the brand asked me to be their global ambassador, I couldn't have wished for a better partnership."
"As fans of my show have seen, I am an advocate of products that use natural ingredients. I am incredibly excited to have this opportunity to work with a brand I believe in and introduce it to people around the world."
Kourtney previously told Refinery29 that Manuka Doctor reached out to her after she listed the brand's products in a blog post about her favourite beauty bits.
"I did a 'good for you glossary' [story] on manuka honey [on my app] and the brand that I was using was Manuka Doctor. The brand happened to be looking for an ambassador for their skin-care line, so they reached out. I love it, it's all natural, it goes with what I believe in for skin care. So, it was a really organic partnership."
Kourtney flew into London at the weekend and has been busy party-hopping and catching up with old friends. She attended the Glamour Awards earlier this week, before meeting up with Lindsay Lohan for a night at exclusive club LouLou's.
