Kylie Jenner spotted puffing on a cigarette as she wears skintight jumpsuit while out on the town with Hailey Baldwin, Gigi Hadid and Kendall

Kylie Jenner was caught smoking while out on Thursday night. I guess she has finally lost it.

The KUWTK TV reality star and Tyga's ex-flame,  was seen lifting a lit cigarette to her lips while hanging out with Hailey Baldwin, Gigi Hadid and sister Kendall Jenner at trendy spot The Nice Guy in West Hollywood.

Kylie lifts the lit cigarette to her lips and appears to take a drag while chatting with friends inside the trendy venue.

Kylie Jenner risked a wardrobe malfunction and flashed a serious amount of underboob in a gravity-defying jumpsuit which had a criss-cross neckline as she headed into the celebrity favorite.

The Keeping Up With The Kardashians star has previously Snapchatted videos of herself blowing smoke rings while puffing on an e-cigareete.

The reality star split from her long-term love, rapper Tyga, and is now said to be dating musical artist, PartyNextDoor.

Kylie's BFF Hailey Baldwin also joined newly single Gigi Hadid and Kylie's sister Kendall for their night out on the town on Thursday.

Social media queen Kylie wore an eye-catching beige jumpsuit that put her cleavage on display.

Climbing out of her bright red sports car, the teenager artfully placed her hand over her assets, making sure all remained in place, showing off her manicured talons in the process.
