Kylie Jenner's app is already beating her sisters and now Caitlyn Jenner's supporting it

The 65-year-old gave her daughter a helping hand in one of her make-up tutorials for Kylie's new official app and website

Caitlyn Jenner makes surprise guest appearance in Kylie Jenner's makeup tutorial 

We might have seen Caitlyn Jenner at odds with some members of her family recently - including an emotional heart-to-heart with ex-Kris Jenner - but it looks like she's on good terms with daughter Kylie.

The teen posted a clip on Instagram that shows Caitlyn making a cameo in a make-up tutorial on her new app and the bonding moment is pretty sweet.

Promoting the new video - which is only available to subscribers of the app and website - she captioned the picture: "A little surprise guest on my new makeup tutorial."

In the cute clip Kylie laughs at Caitlyn's envy over her eyebrows, with the 65-year-old complaining that "they're too perfect".
The Kylie Jenner Official App only launched on Monday but it is already top of the iTunes charts, beating her sisters and even Facebook to the number one spot.

Caitlyn appeared in a tutorial with make-up artist Ariel Tejada to create a “peachy” look and there is much more to come for those who've parted with their cash to get even more access to Kylie's life.

Kylie Jenner has promised we'll get all her beauty and style secrets on the app

She's shown her fans how to boost their cleavage without surgery and also her visit to a children's hospital where she handed out toys.

Promising more special appearances, Kylie wrote on Twitter that she’d be interviewing her “friends” for the app and website - which also launched on Monday.

We wonder how long it takes for boyfriend Tyga to make an appearance?
