All eyes were on Kendall Jenner's Twitter page this evening as her millions of fans awaited a well hyped announcement from the reality TV star. 

Momager Kris Jenner took to Twitter yesterday to share a video of Kendall discussing her 'most raw story' with the world, teasing the clip and encouraging people to tune into Kendall's Twitter tonight. 

'Make sure to watch @KendallJenner’s Twitter on Sunday night to find out what I’m talking about and be prepared to be moved,' she wrote.

'I’m so proud of my darling @KendallJenner for being so brave and vulnerable.'

'Seeing you share her most raw story in order to make a positive impact for so many people and help foster a positive dialogue is a testament to the incredible woman you’ve become.'

Kendall's announcement turned out to be a sponsorship with acne treatment company Proactiv. 

The model revealed that after images of her were released following walking the red carpet at the Golden Globes when she was 21 made her feel even more insecure about her acne, she decided to try the brand. 

Proactiv is well known for it's infomercials featuring celebrities such as Jessica Simpson, Katy Perry and Lindsay Lohan. 

'After the Globes, when Proactiv asked if I’d like to try their products, I thought, ‘You know what, I may as well give it a shot, I’m desperate,' she told Vogue. 

However, fans are giving Kendal mixed feedback to her announcement. 'Everyone gets pimples so….. what's the brave story sis,' tweeted one.

Most seem disappointed that Kendall's hyped reveal is a brand ambassadorship, but it will certainly be empowering for young people to hear a powerhouse like Kendall Jenner discuss how struggling with acne impacted her life.
