No selfies! Caitlyn Jenner gets her coffee fix... but doesn't look very pleased to be spotted by a fan

It's her unwavering morning routine - hop in the car and head to Starbucks.

And Caitlyn Jenner's daily coffee run does not include a pitstop to meet fans, as one found out on Saturday.

The reality star had stopped by her local - perched in a scenic spot beside the PCH in Malibu, California - when she was approached by a star-spotter.

After years in the spotlight Caitlyn - who was previously known as Bruce Jenner before undergoing gender reassignment surgery in 2015 - deftly side stepped the man before continuing on her way.

Caitlyn was dressed down for her outing in jeans and a sweater, but as always looked polished with perfectly applied make-up. 

The 67-year-old star is busy prepping to release her memoir, The Secrets of My Life, which will be released in April this year.

In a new video Caitlyn admitted she endured a 'long personal struggle', but she has finally found happiness with herself.

She said: 'Imagine denying your core and soul. Then add to it the most impossible expectations that people have for you because you are the personification of The American Male Athlete. 

'After a lifetime of secrets... and a long personal struggle... Caitlyn Jenner is finally learning to live as her true self.'

And Caitlyn - who has daughters Kendall, 21, and Kylie, 19, with ex-wife Kris Jenner - has admitted time has been 'moving so quickly' for her over the past few months, she is glad to be able to take some time to "reflect" on her major transformation.

Speaking previously, the Keeping Up with the Kardashians star said: 'Things have been moving so quickly that it will be nice to slow things down a bit and take the proper time to reflect on this journey.

'I couldn't pick a better team... to make sure this story is told with a lot of honesty and care.'

Caitlyn first announced she was working on the memoir in January 2016, and took to social media in November last year to reveal the details of the upcoming publication, and her excitement at the project.
