After much speculation, Travis Scott and Kylie Jenner have welcomed a baby daughter into the world.

The 20-year-old reality TV star and beauty industry entrepreneur shared the surprising news that she and the 25-year-old rapper were officially parents in an Instagram post on Sunday (Feb. 4).

"I'm sorry for keeping you in the dark through all the assumptions," Kylie wrote in a lengthy Instagram post addressed to her fans. "I understand you are used to me bringing you along on all my journeys. My pregnancy was something I chose not to do in front of the world. I knew for myself I needed to prepare for this role of a lifetime in the most positive, stress free and healthy way I know how."

Jenner revealed the baby was actually born on Feb. 1. "I appreciate my friends and especially my family for helping me make this private moment as special as could be," she added. "My beautiful and healthy baby girl arrived on February 1. And I just couldn't wait to share this blessing."

Travis, who was recently added to the Rolling Loud Miami lineup and the Black Panther: The Album tracklist, made the announcement of his daughter's arrival on Twitter. "2.1.18 4 ever New rager in town. !!!" he tweeted Sunday.

He also gave an update on Astroworld, his highly-anticipated third album. "May I supply the rage on this next album. My conscience is on fright night at six flags," he wrote.

The baby was born weighing in at 8 pounds, 9 ounces, which Jenner revealed in an 11-minute documentary that captures her and Travis Scott's journey to parenthood. A brief shot of the baby following the delivery appears as well as many intimate moments like Travis kissing Kylie's baby bump and the two eyeing a pair of Nike sneakers given to them for the baby as a Christmas gift.

Travis and Kylie have been dating since last April, when they were spotted showing some PDA at 2017 Coachella. Their relationship has progressed over the last several months, with the couple getting matching tattoos in June. They have been mostly mum on the pregnancy rumors that have been running rampant, until now.
