In bed with Kim Kardashian: Reality star shares topless snap as she wishes her fans 'goodnight' on Instagram

It was just the day before that she wished her fans 'good morning' with a very busty snap.

And by Monday night Kim Kardashian had upped the stakes as she posted a topless snap of herself to Instagram.

The 37-year-old was clearly in a state of undress as she protected her modesty with some bed sheets while wishing her millions of followers 'good night'. 

The day before, the reality star flashed her impressive cleavage in a photo she captioned 'Morning' along with a sunshine emoji.

Pulling a sneer for the camera, Kim, clad in a denim shirt, also revealed a jeweled grill in her teeth.

The reality TV icon had strung on three necklaces, two of which were medallions and one of which had metallic lettering reading: 'PABLO.'

Kim's husband, Kanye West, released a record in 2016 entitled The Life Of Pablo - his seventh and most recent studio album.

Kanye is Kim's third husband - preceded by Damon Thomas and Kris Humphries - and the pair of them are currently expecting a baby via surrogate.

The couple, who are known affectionately to fans as Kimye, already share four-year-old daughter North and two-year-old son Saint.

As it turns out, Kim's family is expanding on multiple fronts, with her younger sister Khloe, 33, expecting a baby by her Cleveland Cavalier beau Tristan Thompson.

Last year, Tristan and his ex-girlfriend Jordan Craig welcomed their own son Prince.

There is also a swirl of rumors that Kim and Khloe's half-sister Kylie Jenner is pregnant at 20 by her 25-year-old rapper boyfriend Travis Scott.

Meanwhile, the eldest sibling in the Kardashian-Jenner lineup, Kourtney Kardashian, 38, has got three children by her on-and-off paramour Scott Disick.

Mason, their eldest, is eight, while Penelope is five and Reign is three.

The Kardashian girls' rotund younger brother Rob Kardashian, 30, has a one-year-old daughter named Dream by his ex-fiancée Blac Chyna. (Daily Mail)
