Where's Kylie? Pregnancy rumours mount with new photo

After 24 days of family portraits, and fans analysing every one down the last pixel, the Kardashian-Jenners have given the world ... a massive anticlimax.

For more than three weeks, fans had been convinced that the family's photographic advent calendar, featuring images of the extended clan in multiple groupings, would all lead to a Christmas announcement that its youngest adult, Kylie Jenner, is pregnant with her first child.

The 20-year-old, who is dating rapper Travis Scott, is widely rumoured to be expecting, and, once confirmed, would be the third woman welcoming a baby in 2018; Kim and Kanye West are expecting their third child via a surrogate any week now, while her sister, Khloe, last week announced she is pregnant with her first child with her partner, Tristan Thompson.

While fans have been tallying up the tell-tale signs for weeks, they will have to wait just a little longer it seems. Here are five of the best.

1. She was absent from the advent calendar

While everyone from Rob Kardashian to Kendall Jenner, plus a plethora of kids from the clan, appeared in the shots posted each day through December on social media, Kylie Jenner has been conspicuously absent.

After Kim Kardashian West posted the December 25 image, fans were quick to express their disappointment.

"I'm not mad, just very disappointed," wrote one Instagram fan.

DAY 25 MERRY CHRISTMAS

2. She's been AWOL from social media

Her last Instagram post, on December 14, was to promote her make-up line, Kylie Cosmetics. Observers say it's out of character for her not to have congratulated her half-sister, Khloe, on her pregnancy. Unless, of course, she was keeping it on the down low. On Christmas Eve, she bobbed up with a post promoting an interview with Love magazine, which was conducted by none other than her mother, Kris Jenner.

3. She phoned a friend to accept an award

Speaking of her beauty line, it's been a smash, so much Women's Wear Daily awarded her "newsmaker of the year" at its recent beauty awards. But Kylie wasn't in New York City to accept the award, and sent a friend to pick up the gong.

4. The baggy clothes

While we're not a fan of one baggy top leading to a raft of "BABY BUMP ALERT" headlines in the tabloids, Kylie has been taking the oversize trend to a whole new level lately.

5. Her mother can't keep her mouth shut

My brother is expecting a baby and trust me, proud grandmas are terrible at keeping secrets. Kris Jenner keeps posting subtle hints about there being a ninth grandchild on the way, which fans are of course reading into way too much.
