The make-up mogul, 23, matched an off-the-shoulder red crop top with the same coloured leather trousers in a string of steamy snaps.
She applied a light layer of make-up and cast sultry glances at the camera as she ran her hand through her raven locks.
The California sunshine lit her garden behind her, highlighting her chic furniture set-up and water features.

The Keeping Up With The Kardashians star was recently applauded for a huge donation of $500,000 to a teenage cancer ward.
The donation was made in honour of her friend Harry Hudson, a cancer survivor, with the money going toward a new lounge for the patients.
“I am so grateful for Kylie’s friendship and the impact she’s had on my life and my cancer journey,” Harry, who was diagnosed with Hodgkin’s lymphoma in 2013, said.
“She has always been there for me, and together, we wanted to figure out a way to be there for other young people who are battling this disease.
“With the help of Teen Cancer America, we were able to contribute the first Hey, I’m Here For You Teen lounge at Children’s Hospital at Vanderbilt — a comfortable space for young people undergoing treatment to pursue their passions.”
He added: “The space will be built at the hospital in Nashville, described as “one of the [US’] leading children’s hospitals.”
It’s set to feature a number of video game set-ups, a big screen TV for movie nights, a meditation space and an area for parents to chat.
And Harry poured even more praise on pal Kylie on Instagram, writing: “Today is a beautiful day!
“A couple years ago @kyliejenner & I raised money to build a center for teens going through cancer in hopes of making their experience a little better.

“Today we are so excited to finally announce the completion of the first #HeyImHereForYou Lounge @vumcchildren in Nashville.
“This space is the initial program of my new charity @hihfycharity which is focused on enhancing the lives of teens and young adults undergoing cancer treatment.”
Kylie had also started fundraising back in 2017, allocating part of her Kylie Cosmetics Birthday collection proceeds to Teen Cancer America.
