Kylie Jenner has announced she has given birth to a baby girl, following months of speculation over whether she was pregnant.
The reality TV star, who shot to fame through Keeping Up with the Kardashians, confirmed that rapper Travis Scott is the father of the child.
The baby was born on Thursday, February 1 (US time).

In an Instagram post, Jenner apologised to her fans for "keeping [them] in the dark".
"I understand you're used to me bringing you along on all my journeys. My pregnancy was one I chose not to do in front of the world," she wrote.
"I knew for myself I needed to prepare for this role of a lifetime in the most positive, stress-free, and healthy way I knew how.
"There was no gotcha moment, no big-paid reveal I had planned. I knew my baby would feel every stress and every emotion so I chose to do it this way for my little life and our happiness."
Jenner also posted a video on YouTube, complete with interviews with friends and family, which detailed Jenner's pregnancy journey.
Speculation that Jenner was pregnant has been rife for many months.
Superstar half-sister Kim Kardashian also fanned the flames by omitting Jenner from the customary family Christmas card, and opting to drink a sardine smoothie rather than answer a question on The Late Late Show with James Corden.
Kardashian herself recently gave birth to a daughter of her own, Chicago. The newborn is her third child with hip-hop artist Kanye West.
