Kendall Jenner is "all about freeing the nipple".
The 20-year-old model revealed she prefers to either go braless or with her lingerie exposed as she likes to show off what's under her clothing.
In a post on her website, KendallJ.com, she wrote: "Lately, it's like I'm either braless or I have my bra out, lol. I'm all about freeing the nipple!
"I just think it's cool to show off what's under your shirt - whether that's a cute bralette or just skin (sic)."
The Free the Nipple campaign is popular with celebrities and is named after Lina Esco's 2014 movie 'Free the Nipple'.
It aims to advance gender equality and oppose sexual objectification.
Meanwhile, Kendall's post comes after it was revealed that she and Harry Styles have ended their on/off romance.
The pair only recently rekindled their relationship and enjoyed a series of dates in Los Angeles but Kendall decided to cool things down because she "refuses to get caught up in the One Direction singer's drama," Us Weekly reports.
Instead, according to the publication, Kendall is moving on with 27-year-old rapper A$AP Rocky.
Kendall's decision to call time on the relationship comes just weeks after it was claimed she wanted to settle down with Harry.
However, he has allegedly been reluctant to get serious with the model, who he was first linked to in 2013.
An insider explained: "Harry has always been 'that guy' for Kendall. She would love to be in a real relationship with him, but he's always had issues settling down in the past with her because he has that rock star mentality."
