BIKINI BOOTY: Kylie bared a whole lot of cheek in her one-piece

But then again, most of us don't have a millionaire fashionista as a matriarch.

Kylie Jenner brought sex appeal to her mansion pool after borrowing one of mum Kris' vintage swimsuits.

The 18-year-old made us all achingly jealous as we languish in the British rain as she dealt with the scorching heat in Calabasas, California.

Stealing a vintage white Chanel one-piece from Kris' wardrobe, Kylie took a dip in her pool and showcased a whole lot of booty while she was at it.

REAR OF THE YEAR: Is Kylie taking Kim's booty crown?

The high-cut thong displayed her rear to maximum effect, with the star baring major cheek as she floated on a pair of inflatable red lips.

Who knew Kris had such raunchy style back in the 80s?

This isn't the first time Kylie has nicked Kris' swimwear.

She previously wore an eye-catching high-cut neon swimsuit which her mum had rocked in the 80s.

NAKED AMBITION: Kylie's latest suit matched her skintone

Not that Kylie really needs to nab swimwear from her family.

The teenager seems to be wearing a different swimsuit or bikini every single day, her latest being a nude number that gave the illusion of being naked – save for the slogan "pleasure" stitched across the chest.

The lip kit mogul is currently single after splitting from rapper Tyga, who has been opening up about their break-up.

Speaking to Big Boy TV, the rapper said: "When you're in a very public relationship like that, it's hard for other people to see you differently than that. It took a lot, career wise, everything. It overshadowed a lot of my talents and a lot of things that I worked hard for."
