Kardashian clan members Kendall and Kylie Jenner have released the second instalment of their young adult novel series, entitled The Time of the Twins.
Meanwhile, rumours are circulating that Kylie is pregnant with Tyga, just after his ex Blac Chyna welcomed a child with the Jenners' half-brother, Rob Kardashian.
Gossip websites claim Kylie, 19, was seen at her OB-GYN's office this week, after the young make-up mogul apparently became clucky while babysitting Blac Chyna's child King Cairo.
The sisters' novels are post-apocalyptic tales of sisterly love set in a dystopian future.
The Time of the Twins picks up where 2014's Rebels: City of Indra left off with a cliffhanger ending, with Lex and Livia embarking on a quest in hopes of escaping doomed city Indra and meeting their birth mother, Delphia.
"We kinda wrote one section for Lex, one section for Livia kind of a thing, so it bounced back and forth," says Kendall.
"Now that they know each other, it's more third-person, but it does give a good idea of what's going through their heads," adds Kylie.
In addition to releasing the new novel, the Jenners have launched a website that features further lore, exclusive videos, quizzes and more.
