Reality TV star Brody Jenner uses partner's breast milk to make coffee: 'It's delicious'

Reality TV star Brody Jenner has shared the secret to making the perfect morning coffee: Breast milk.

The son of Caitlyn Jenner, whose famous half siblings are Kendall and Kylie Jenner, welcomed his first child with much younger fianceé Tia Blanco in July and is documenting their parenting journey on their YouTube channel.

The Brody & Tia channel has amassed 19,000 subscribers and so far shared two videos. The first, The Birth of our First Daughter, came two months ago while the latest, First Month with our Newborn, was shared just last week, and captures the moment Jenner uses Blanco's breast milk to make their morning coffee.

"So I just came out to make us both some coffee and we are out of almond milk, but I did find out thing," he announces, before the video shows him proudly holding a bag of breast milk.

"Now, I hear great things about breast milk. I hear it's very nutritious. I hear it's very delicious and I think it will do," he continues, before wisely going to seek the opinion of his fianceé, who is laying in bed beside their sleeping daughter, Honey.

"Sorry to disturb you but we are out of almond milk. Do you mind if we use the breast milk that I put in the fridge last night?" he asks.

"No, it will be really good for you," she replied.

The video then shows Jenner whipping up a couple of breast milk lattes before he returns to the bedroom, where Blanco has fallen asleep.

"Do you want your breast milk latte? Babe?" he asks, before apologising for waking her up.

The two then sit in the bed together and enjoy their coffee.

After sampling his cup, he ponders for a few moments, before announcing it is 'delicious'.

"It just tastes like coffee," his fianceé replies.

Jenner, 40, and Bianco, 26. a professional surfer, reportedly met a year ago in Hawaii.

Jenner, a former star of various reality TV shows, including The Princes of Malibu and The Hills, was previously married to Kaitlynn Carter, whom he wed in Bali.

After the pair split, Carter went on to have a short relationship with Miley Cyrus.

Jenner announced the arrival of Honey Rae Jenner on Instagram.

Among those to congratulate him was former step sibling Kim Kardashian.
