Kendall Jenner has been offering Caitlyn Jenner style advice.
The 19-year-old model has reportedly played a huge part in the reality star's wardrobe choices as she valued her daughter's advice, and the teenager even helped with the 'I Am Cait' star's look for the ESPY Awards, where she won style praise for the white dress she donned to pick up the Arthur Ashe courage award.
A source said: "When it comes to style, there's no one's opinion Caitlyn respects more. As she embraces the next chapter of her life - with all eyes on her - she knows Kendall is the person to help.
"It's unbelievable how many people are laying claims to Caitlyn's style, when the only person she listens to is someone who doesn't brag about it - Kendall.
"Caitlyn's finest fashion moment, including when she gave an impassioned speech at the ESPY Awards wearing a floor-length Atelier Versace dress happened because Kendall pulled a few strings."
And Caitlyn - who was known as Bruce Jenner before her transition - isn't the only member of Kendall's family to turn to her for fashion tips.
The source added to LOOK magazine: "Everyone goes to her for advice. Khloe, Kim and Kourtney have all been 'Kendalled'- they love stealing her designer clothes, even any cast-offs."
