In addition to giving Alabama some new designer accessories, Travis and Kourtney also made her day extra special by decorating their home with bouquets of light pink roses and rose gold balloons spelling out "2-0."
And for a sweet touch, they served up what appeared to be turmeric lattes reading, "I heart Alabama."
Alabama's last year of being a teenager was certainly a big one, as she debuted a new romance with UCLA football player Scooter Jackson in March and adopted her own French bulldog in May. She's also grown into her own by learning how to confront haters head-on, including clapping back at critics of her relationship back in October.
“You really win in the end when people are hating on the fact that I got flowers from my boyfriend," she shared in a social media video at the time. "Give it up. You look miserable, you’re hating, and I’m happy."
Beyond celebrating Alabama's birthday, the festivities are just getting started for the Kardashian-Jenners this holiday season. Read on to see how they've been celebrating ahead of Christmas.
Khloe Kardashian and her daughter True Thompson, 7, made chewy Christmas cookies together to get in the holiday spirit, as Khloe shared on Instagram Dec. 24. True gave a full tutorial on how to make the festive treat with some help from her mom, who True decided was the perfect baking partner. When the cookies came out of the oven, True shared, "The cookies smell so good, I wish you could smell them from the camera."
Kourtney Kardashian's stepdaughter Alabama Barker marked her 20th birthday on Christmas Eve, giving a glimpse at the celebrations.

Kylie Jenner debuted her annual 2025 Christmas wrapping, this time opting for a bold leopard print. As she put it, "Was feeling fun this year."
Kim struggled to get kids North, Saint West, 9, Chicago West, 7, and Psalm West, 5, into a family photo ahead of Christmas, quipping on Instagram Dec. 22, "I really tried."
Khloe took the next generation of Kar-Jenner to the Happiest Place on Earth, posting a selfie with her kids True and Tatum Thompson, 3, as well as their cousins Dream Kardashian, 9, Chicago and Psalm. Khloe captioned the Dec. 22 snap, "Disneyland with my elves."
