Kylie Jenner debuts her bump for the first time as she hides pregnant figure under baggy clothes (Details, pics)

Is she or isn't she - Kylie Jenner's teen army have been hotly debating this question since pregnancy reports first surfaced.

The 20-year-old, who has yet to officially confirm or even comment on her happy news, was pictured boarding a private jet for Kris Jenner's 62nd birthday celebrations on Sunday morning. Well now the argument can seemingly be settled - after the reality star was pictured for the first time since news of her impending motherhood was leaked.

But despite swamping her petite figure with the wintry sweater and sweatpants, it was quite clear Kylie was expecting. Noticeably heavier around the midriff, the make-up millionairess hid her bump under baggy clothing.

The father is her boyfriend music rap star, Travis Scott. The two only began dating back in April, and although Kylie has embraced her pregnancy, it is not thought to have been planned.

Along with her sister Khloe, 33, who has been similarly (and equally uncharacteristically) closed mouthed, Kylie is said to be expecting her first child early next year.

Their mother Kris Jenner has even joked she is waiting until the new Keeping Up With The Kardashians series to potentially confirm her daughters' pregnancies - because she 'gets 10 per cent'. The Kardashian family have closed ranks around both Kylie and Khloe, refusing to speak about their pregnancies - an unusual move for the publicity hungry clan.

After a grilling about the subject on The Ellen DeGeneres Show this week, the momager remained coy, refusing to be 'tricked' into confirming the speculation.

The Kardashian-Jenner clan recently penned a deal worth a reported $150 million for more KUWTK series. Three new babies - sister Kim is expecting via surrogate - are clearly an attractive potential storyline for the long-running show.

Meanwhile, while Kylie has ditched her nights out on the town, the canny businesswoman certainly hasn't deserted her social media followers. However the midriff baring bikini shots have been swapped for lots of close ups of her face, and pictures of her various nail colors.

On top of this there have been plenty of stories, credited to 'sources' - giving details of her parenthood plans. It's believed the brunette beauty has hired an entire team of people to help make carrying her unborn tot as easy as possible.

One source said: 'Kylie hired a pregnancy coach... who will help her with nutrition and exercise, as well as take her through Lamaze training when she gets further along. Kylie is definitely not taking any chances when it comes to her unborn baby!'

The Life Of Kylie star is also said to have beefed up her security in the run up to the birth, as well as hiring four new assistants to help with the running of her business.
