Kylie Jenner Jokingly Wishes Sister Kendall, 28, a 'Happy 30th!' with Sweet Floral Birthday Tribute

The makeup mogul teased her older sister about turning 30 on her 28th birthday

Kylie Jenner is a jokester!

The makeup mogul, 26, teased sister Kendall Jenner about turning 30 — despite the model celebrating her 28th birthday on Friday — as she sent her flowers to mark the occasion.

Kendall shared a photo of the bouquet of sunflowers sent to her from Kylie on her Instagram Story, which could be seen paired with a card that read, "Happy birthday sister 30 years old!!!! Times flies. Love you, Kylie."

In response, Kendall wrote "Lmao" and included a middle finger emoji, as Kylie added a crying laughing face emoji in her own response when she reshared the photo on her social media account.

Kylie — who dropped Khy, her first clothing collection, earlier this week — also shared a behind-the-scenes photo of Kendall’s birthday celebrations, in which she could be seen enjoying four birthday cakes.

In the snapshot, Kendall sat in front of a giant white birthday cake that was lit with candles and had a photo of her as a child enlarged on the front.

The model smiled in a white off-the-shoulder dress as her hair partially covered her face.

Elsewhere on the table were three other white circle-shaped cakes with lit candles placed on top. Two displayed the message "Happy Birthday Kendall" in icing, while the other read, "Twenty ATEEE."

“Happy birthday @kendalljenner 🤍🤍,” Kylie captioned the celebratory snap.

The rest of the Kardashian-Jenner family also shared birthday tributes to Kendall on Instagram Friday. Matriarch Kris Jenner wrote, “Happy birthday to my beautiful, kind, generous, giving, smart, talented, creative, amazing, and thoughtful daughter Kenny!!”

Kris, who turns 68 on Sunday, added, “You are such a special and amazing daughter, sister, auntie, and friend and I am beyond blessed that God chose me to be your Mommy. I love you soooo much my beautiful girl… Mommy xo.”

Sister Kim Kardashian, meanwhile, wrote in her own tribute, "Happy Birthday my beautiful Horse Girl KJ! Our road trips and our travels will always be my favorite memories together and I can’t wait to create even more! You always bring the grounding energy we all need. You are such a light! I pray this year will bring you peace and more love and happiness."

She added, "You are the True definition of a jack of all trades…Model, tequila queen, DJ, photographer, animal lover, health extraordinaire, adrenaline junkie, arm wrestling champion….. this list would be massively long if I wrote every single thing you excelled at.
