Kourtney Kardashian and Travis Barker are continuing to bask in the glow of becoming parents once again, as they dote over their nearly two-month old son Rocky Barker.
However, the couple are celebrating another special milestone in their lives, that being the birthday of Travis' daughter Alabama Barker, who turned 18 on Christmas eve.
Travis, 48, shares Alabama and her brother Landon, 20, with his ex-wife Shanna Moakler. During their marriage from 2004-2008, he also developed an extremely close relationship with Shanna's daughter from her previous fiancée, Atiana.
Kourtney, 44, took to her Instagram Stories to share a sweet birthday message for her stepdaughter, posting a snap of the pair dressed in chic patterned luxury streetwear.
She wrote alongside it: "You're such a blessing in my life @alabamaluellabarker, happy birthday! [heart emoji]," and Alabama revealed on her Instagram the incredible gift she received from Kourtney.
The Poosh founder gifted her stepdaughter a beautiful and delicate diamond necklace, covered completely in sparkling stones. She wrote: "Thank you Kourtney! I'm in love!"
Blink 182 drummer Travis shared a sweet compilation of photos on his own social feed as a tribute to his daughter, spanning her birth and childhood to the present day.
"Happy Birthday my beautiful daughter," he penned. "I can't believe my baby is 18 and all grown up. Being your Dad is the biggest joy in the world.
"May you be surrounded by love and all your favorite things today and forever! I'm so proud of you and I love you so much," he added, receiving a heart emoji from Kourtney as well.
