Kylie Jenner was the image of the classic busty bombshell when she posed up a storm on Instagram over the weekend.

The 26-year-old posted a couple of sizzling snaps advertising apparel from the Los Angeles–based activewear brand Alo.

Accentuating her screen siren features with makeup, the lip kit mogul wore her luxurious waves of jet black hair down.

She could be seen modeling a plunging sports bra that not only served up a generous helping of cleavage but also allowed her to bare her taut midriff.

Her latest Instagram update comes after her mother Kris Jenner gave her imprimatur to Kylie’s blossoming romance with Timothée Chalamet.

Timothée and Kylie have been linked since April of this year, although they have both studiously refrained from discussing the relationship in public.

However Kris dropped a hint on her Insta Stories last weekend, hours before Timothée was due to host Saturday Night Live.

The 68-year-old ‘momager’ reposted a promo for Timothée’s Saturday Night Live sH๏τ and plugged: ‘Tune into SNL tonight!’

Timothée, whose dating history includes Eiza Gonzalez and Lily-Rose Depp, has repeatedly hit the headlines for his current runaround with Kylie.

After being trailed by rumors for months, Kylie and Timothée took their romance public by kissing in the stands at a Beyonce concert near the end of the summer.
