Travis Barker shares sweet tribute to ‘beautiful’ daughter Alabama on her 18th birthday as stepmom Kourtney Kardashian gifts her diamond necklace: ‘Can’t believe my baby is all grown up’

Travis Barker proved to be a doting father as he lavished praise on his daughter Alabama on her 18th birthday, which falls on Christmas Eve.

The 48-year-old Blink-182 drummer – who recently welcomed son Rocky with Kourtney Kardashian – went to his Instagram to post adorable throwback snaps with his beautiful daughter, whom he shares with his ex Shanna Moakler.

“I can't believe my baby is 18 and all grown up,” the rock star wrote alongside the adorable photo carousel.

'Being your father is the greatest joy in the world. May you be surrounded by love and all your favorite things today and forever!' he continued. “I'm so proud of you and I love you so much.”

The sweet shout-out comes after Alabama revealed her stepmother Kourt gifted her a beautiful diamond necklace.

In her Instagram Stories, Alabama modeled the beautiful bling in a black robe with the caption: “Thank you @kourtneykardash. I'm in love!'

The blonde beauty also shared a clip of herself dancing in a sassy sheer black dress with a floral pattern and another sexy photo of herself eating a cupcake while wearing only a bomber jacket.

Kourt's lavish birthday gift comes as no surprise as she and Alabama quickly bonded after the POOSH founder started dating Travis.

The teen was even seen at the couple's Italian wedding in May 2022.

The famous couple formally became husband and wife on May 15 of that year in a private ceremony in Santa Barbara, with only Kourtney's grandmother and Travis' father in attendance.

Before that, they had an impromptu wedding in Las Vegas after the Grammy Awards on April 3, following Travis' performance at the event.

Despite being officiated by an Elvis Presley impersonator, that wedding was not considered official because they had not obtained a marriage license beforehand.

The wedding is also Kourtney's first attempt at tying the knot.

The sweet shout-out comes after Alabama revealed her stepmother Kourt gifted her a beautiful diamond necklace.

Although they dated for ten years, Kourt never married Scott Disick, the father of her three children Mason, Penelope and Reign.

Meanwhile, Travis has been married twice before: to former model Shanna from 2004-2008 and to author Melissa Kennedy from 2001-2002.

The Blink-182 drummer and Shanna share son Landon, 20, as well as daughter Alabama.

Travis previously revealed that his daughter's name was inspired by the character Alabama Whiteman in the movie True Romance, Travis's favorite movie.

Meanwhile, Kourt and Travis welcomed their son Rocky Thirteen Barker on November 1.

In her Instagram Stories, Alabama modeled the beautiful bling in a black robe with the caption: “Thank you @kourtneykardash. I'm in love!'

The couple shared a first look at their baby boy, Rocky, in sweet family vacation photos shared to the reality star's Instagram page.

The Poosh founder captioned the carousel of photos with “ROCKY,” followed by a black heart emoji.

The Kardashians star has given birth to their baby boy just two months after undergoing 'terrifying' fetal surgery to save her unborn son's life.
