On one level, it's the news that took us - and everyone else - aback.

Then another level, and on reflection, we're also not all that surprised either. Congratulations to Kylie Jenner and her beau, Travis Scott: multiple US sources confirm the pair are expecting their first child together. Kylie, 20, and Travis, 25, got together in April and are said to be head-over-heels in love. Here, we look at the 11 things we know - so far - about Ms Jenner pregnancy.

1) She's four months' along The happy duo have only been together for five months, but their romance has certainly been whirlwind. Kylie is said to be four months' along and has started to show the early signs of a bump. Travis and Kylie already also have matching butterfly tattoos on their ankles and are inseparable. 2) She told her mates at a music festival  Kylie seemingly had planned to keep the news under wraps for a bit longer - but at a music festival, where she was sipping on water and taking it easy, she confided in her closest friends. 3) They are having a girl Kylie has had a prenatal gender test done - at around the 10-week mark - and has been told that the baby is a girl.

4) They're on cloud nine Although Travis and Kylie haven't been together for all that long, both are said to be ecstatic at the prospect of being parents. A source told People: "It is an unexpected but completely amazing turn of events that she could not be more excited or thrilled about." 5) Tyga has already weighed in Ms Jenner's former long-term love - rapper Tyga - has already chipped in his tuppence worth. On Friday as the happy news broke, he Snapchatted a message which read: "Hell nah that's my kid!" He included a screengrab of a headline announcing her pregnancy and a picture of Ms Jenner. He later deleted the Snap. 6) The baby was conceived in Miami It is likely that Travis and Kylie conceived their baby in Miami. An episode of Keeping Up With The Kardashians filmed four months' ago shows Kylie going on a charity trip to Peru. Rather than travelling from her Californian home, however, her private jet collected her in Miami - where she has been spending a romantic few days with her boyf. 7) She's covering up Kylie is well-known for sharing a load of gorgeous pics with her fans via her social media accounts. However, in recent weeks she's been a lot more restrained - posting more throwback and older photos too. She's also been seen donning baggy t-shirts rather than her usual array of crop-tops. 8) Kylie wants to be a young mum She's already stated on KUWTK that she feels "like 30 is too late" for starting a family, adding: "Every psychic said that I’m only going to have two kids." On an episode of I Am Cait, she stated that she wanted to be a "young mom". Her own mammy, Kris, was just 23 having Kourtney - the eldest of the Kardashian-Jenner clan. 9) That's one lucky baba Kylie might only be 20 but she's amassed a fortune through reality TV, sponsorship deals, makeup and fashion lines. She own an incredible €10million home in the Hidden Hills area of California and has several investment properties too. Forbes says Kylie is worth €16.5million and her iconic lip-kits and eyeshadow collections have pulled in €350 million in retail sales in the last 18 months alone. 10) Travis is being protective  This will also be a first baby for Travis Scott - he's proud-as-punch and has been sharing the happy news with close friends and family for weeks. An insider told People that Mr Scott is "so excited". They added: "He’s been so affectionate and protective of Kylie since they found out. He can’t wait to be a dad."

11) She's feeling great Although big sis Kim was plagued with issues while expecting, Kylie's pregnancy has been really straightforward and she's been largely free of the likes of morning sickness. She's told her family she's now full of energy and has been sleeping really well.
