Khloe Kardashian has hinted that a member of her family is pregnant.

The 'Keeping Up with the Kardashians' star - who filed for divorce from her husband Lamar Odom in late 2013 after four years of marriage - took to picture sharing site Instagram to post a picture of a positive pregnancy test and teased in the caption that it belonged to either herself, one of her famous siblings Kim or Kourtney, half-sister Kendall Jenner or her mother Kris Jenner.

She wrote alongside the picture, which was later deleted: ''Who's pregnant? Kim, Khloe, Kendall.''

The brunette beauty also posted pictures of herself, with her sisters and mother, but quickly dismissed the possibility it could be the showbiz matriarch's test by writing: ''I think we could rule Miss Menopause out of this equation.''

Khloe's post followed the release of a trailer for an upcoming episode of the family's E! reality series which showed her in shock after she was presented with a positive pregnancy test.

The advert also shows Kim, 34 - who has an 18-month-old daughter with her husband, rapper Kanye West - having an ultrasound scan, with her doctor saying: ''We want to see another pregnancy some time soon.''
