Oh, baby, baby! Kylie Jenner stepped out on Sunday, Sept. 24, to support her boyfriend, Travis Scott, during his performance on night two of Las Vegas’ iHeartRadio Music Festival. Though the 25-year-old rapper killed it onstage, we can’t deny the fact that pregnant Kylie’s growing baby bump was the real star of the show. The Keeping Up With the Kardashians personality, 20 — who is reportedly four months pregnant — rocked a T-shirt at the festival, which clung to her expanding tummy. Check it out in the video below!

It’s only been a few days since the world collectively gasped upon hearing Kylie’s pregnancy news. As People reported on Friday, Sept. 22, the cosmetics mogul is due in February and expecting a baby girl. While the pregnancy was reportedly unplanned, a source told the outlet that Kylie and Travis are thrilled to start a family.

“They started telling friends a few weeks ago. The family has known for quite some time. She is really excited and so is Travis,” said an insider, while another source added, “It is an unexpected but completely amazing turn of events that she could not be more excited or thrilled about. Everyone is overjoyed for her. This is the happiest she’s ever been.”

Indeed, Kylizzle has always been vocal about wanting to become a mother sooner than later. “I want kids for sure,” she said during a February 2016 episode of Kocktails With Khloé. “I feel like seeing you guys go through everything, it’s great knowledge. I feel like I want kids before I’m 30.”

Prior to Kylie’s admission on Kocktails, she said that she actually wanted to start a family before she turns 25, because 25 was “too late.” She has also said that “every psychic” she has ever consulted has told her that she is going to have at least two children.
