The young socialite took to Instagram to flaunt the valuable gift.

In the photo, Alabama wore a thin diamond necklace with a plunging black top.

Her face was cropped out of the image so that all eyes were on the timeless piece.

She did not disclose the cost of the timeless necklace, but with Kourtney’s net worth close to $66million, it is sure to be a valuable gift.

Travis Barker’s daughter captioned the post: “Thank you, Kourtney Kardashian! I’m in love.”

BIRTHDAY GIRL

Travis Barker’s daughter flaunted her curvy figure as she donned a black strapless dress in a risque series of Instagram Stories.

In the first Story, Alabama, 18, took a mirror selfie as she flashed her bare chest and showed off her birthday outfit.

The TikTok star displayed her sharp fingernails and accessorized with a silver necklace and matching ring.

In the second Story, Alabama displayed her backside and teased her booty as she sat on her white bed.

Above the headboard, the balloons spelled out: “Happy Birthday.”

EARLY PRESENT?

Alabama’s birthday posts came after she hinted about getting lip fillers as a possibly present for herself.

In the cropped image, the teen influencer showed off her plump lips while wearing a khaki hoodie.

She wrote: “Birthday lips!” and added red lips emojis.

After tagging the surgery clinic, the facility re-shared her photo on their official Instagram account and added an injector needle emoji.

FLAUNTING WEALTH

Kourtney’s diamond necklace gift to Alabama must seem like mere chump change when living such a lavish lifestyle.

Earlier this year, Kourtney showed off her nearly $500 daily supplement routine.

Later in the year, she shared a photo of a $530 skull lamp from Travis Barker’s homeware line.

Alabama is in line to inherit all of Kourtney’s wealth as she showed off a handbag valued at $1,300.
