"Happy Birthday Daddy!" reads the billboard, which features a close-up black-and-white shot of Travis and Kylie's 1-year-old daughter, Stormi, as well as a photo of Kylie posing with the baby girl. The mother-daughter duo sports matching white one-pieces in the pic as they cuddle up against a crisp white background. "Love, Mommy & Stormi XO," Kylie added.
Kendall Jenner also made news on Friday as she posted a slideshow to her Instagram with hilarious commentary on her sisters' many kids. After a sweet family photo featuring Kylie's, Kim Kardashian West's and Kourtney and Khloe Kardashian's families, Kendall shared meme reading "Pregnancy is in the air. Me:" with a photo of a woman with a plastic bag over her face.
Life has definitely changed for Kylie since she became a mom in February 2018 -- but her friends knew parenthood was always in the cards for her.
"Well, I always remember, you know, Kylie saying she always wanted to be a mom and she really felt like that's what she was meant to do in life," Pia Mia recently told ET. "So, I feel like it really didn't change. Like, Kylie is so mothering and she's just such a sweet, loving person in general and I just think that now it's just more, maybe."
