They looked stylish too — Kendall, 21, pairing grey pants with a white turtleneck sweater and shearling jacket (which she wore casually over her right shoulder). She added pointy black heels and rectangular sunglasses to her outfit, trading out a bag for a black fabric body pouch that strapped around her waist and over her shoulder.
Kris, meanwhile, dazzled in a long black sequin jumpsuit with sheer patterned cutouts. The 60-year-old momager accessorized her look with black heels, a diamond bangle bracelet and oversized shades.
While sitting in the front row, Kris spoke out to The Cut for the first time since Kylie’s pregnancy news broke, refusing to directly address the news but instead saying that “something happens every single day.
“You never know what is going to break at any moment,” she said.
“They started telling friends a few weeks ago,” said the source of the Keeping Up with the Kardashians star and her rapper boyfriend. “The family has known for quite some time. She is really excited and so is Travis.”
“Everyone is overjoyed for her,” the source said. “This is the happiest she’s ever been.”
Another source told PEOPLE that Kris was “shocked” by her youngest daughter’s baby news but that she ultimately wants what is best for her.
“It definitely took some getting used to,” the source said. “But Kylie has always been very headstrong, she’s always wanted to do her own thing despite what Kris says. Of course Kris just wants the best for her daughter and loves and supports her no matter what.”
Another insider said Scott began telling friends about the pregnancy in July. “He was so excited he couldn’t keep it in,” says the insider. “He’s been so affectionate and protective of Kylie since they found out. He can’t wait to be a dad.”
The insider added Kylie was worried people would find out she was pregnant before she was ready to share the news, so she “started posting old photos of herself on social media” that flaunted her flat stomach.
“Kylie was really surprised but is so happy,” said the insider. “She wants to be a mom.”
Reps did not respond to PEOPLE’s request for comment.
Kylie has been dating Scott since earlier this year after splitting from her on-again, off-again boyfriend Tyga in April.
The star’s baby won’t be the only new member joining the famous KarJenner brood:older sister Kim Kardashian West is also expecting via surrogate. Kardashian West shares two other children with husband Kanye West, Saint, who is 21 months old, and daughter North, who turned 4 in June.
Kris is also glam-ma to son Rob Kardashian‘s daughter Dream, 10 months, and daughter Kourtney Kardashian‘s three children: Mason, 7, Penelope, 5, and Reign, 2.
