Justin Bieber's lady loves of past and present collide as Kourtney Kardashian and Hailey Baldwin are seen heading into West Hollywood hot spot together
He reportedly dated Kourtney Kardashian, 36, in the fall.
And this holiday season he romanced model Hailey Baldwin, 19, while in St Barts.
So it was odd to see Justin Bieber's two ladies party together on Monday night at The Nice Guy in West Hollywood.

Biebs' babes on the town: Kourtney Kardashian and Hailey Baldwin, who have both been romantically linked to Justin Bieber, partied together on Monday night at The Nice Guy in West Hollywood
Girl free: The Sorry singer was solo on Sunday afternoon in Beverly Hills
The E! star clearly wanted to upstage the Sorry's singer's current darling as she wore a see-through top that exposed her bra.
Baldwin showed off her legs in a mini skirt.
Both looked as if they were ready to have some fun. The chart topper was not seen, but Kendall Jenner and Pia Mia were there too.
Sexy style: Kardashian stood out in sheer black top and exposing her bra
As well as flaunting her cleavage, toned stomach and slim waistline under the transparent t-shirt, Kourtney drew attention to her petite frame with her stylish flared trousers.
The mother-of-three covered her legs with a pair of low-slung black flared bottoms while wearing a slick blazer caped over her shoulders.
Kourtney added a touch of 90s glam thanks to a choker necklace and wore her hair scraped back in a high ponytail.

Look suave in a Saint Laurent tuxedo blazer like Kourtney
Kourtney Kardashian was spotted look very dapper as she headed for dinner in LA wearing wide leg trousers teamed with a sheer top and Saint Laurent tuxedo blazer. Kourtney then accessorized her look with a black choker, pointed heels and a navy leather clutch bag for a look that definitely meant business!
One of the most iconic of Saint Laurent's designs, if not the twentieth century, the 'Le Smoking' tuxedo jacket was first designed in 1966. At the time it was a pioneering move that made way for women to wear trouser suits and the power dressing movement.
A great investment, it's safe to say if this jacket has stood the test of time for the last fifty years, it should see you through the next couple of seasons!

Business chic: Kourtney, 36, was rocking a smart blazer and matching trousers, upping the sex appeal with the semi-sheer T-shirt
If she was feeling at all fatigued from her previous night out, she didn't show it as she looked as dewy and fresh-faced as ever, with little more than a heavy smoky eye for the evening.
On Sunday, Kourtney had accompanied her youngest sister - Kylie Jenner - to a Golden Globes party on Sunday.
Meanwhile, her second-youngest sister Kendall, 20, looked typically sensational as she stepped out alongside her on Monday for dinner.

Kendall, who is rumoured to be dating One Direction's Harry Styles, turned heads in a stylish grey crop top that flaunted her perfectly flat stomach and tiny waist.
Her lean figure was accentuated by the rib-tickling length of the cosy knitwear and its elasticated hemline, her pancake-flat stomach and whittled waistline stealing the show.
The reality TV star-turned-model dressed up the look with a pair of smart black trousers - with a flattering low-slung waistband across her tiny hips - and cute snakeskin print stilettos.

She completed her simple but effective smart-casual look with a small black bag with a cute pom-pom attached.
She wore her dark locks down loose and stayed true to form by wearing minimal make-up, a look that makes her stand apart from her more cosmetic-loving sisters.
Hailey, 19, opted for an equally daring look, donning a tiny, thigh-skimming dress with a very short hemline.

Sneaky treat: Kourtney shared a snap on her Instagram later in the evening showing her chowing down on a snack along with a squirrel emoji
Justin Bieber's new squeeze wore her blonde tresses down in pretty curls and set off the look with a pair of simple heels.
The starlet has just returned from a holiday to Mexico with the singer, where Bieber's bad behaviour sensationally saw him booted off the site of some ancient Mayan ruins.
Last week, the 21-year-old was reportedly asked to leave the archaeological site of Tulum after he arrived carrying open beer cans, climbed on some of the protected structures and 'mooned' other tourists.
