Khloe felt festive as she posted two photos of her lavish Christmas decor in her Los Angeles home.

Following this, Khloe took a trip down memory lane through old photo albums.

She found previous family snaps, which the Kardashian clan take every year.

The Good American founder uncovered an old photo of her sister Kendall when she was younger.

Although the date was not specified, it looked as if Kendall was around 5 years old.

Khloe posted a photo slightly zoomed into Kendall on the first story.

She wore a puffy black dress with sleeves and a huge white collar detail.

Her hair was pulled up into pig tails and she looked at the camera seriously.

The people surrounding her in the photo were not clear or named, but fans could see shoes behind.

‘PLOTTING’

Khloe captioned the photo: “The amazing case of Kendall Jenner.”

The next photo uploaded by Khloe was exactly the same, but zoomed in a bit closer on Kendall’s face.

Khloe wrote: “She’s definitely plotting something.”

She again posted the same photo, but this time completely zoomed into just Kendall’s face so nothing was visible around her.

Khloe did not add any comments or music to the last photo.

Her next story was of a huge bouquet of pink flowers gifted to her.

‘I LOVE YOU’

Khloe is no stranger to posting her family life on social media, with her wishing her nephews a happy birthday on Thursday.

Sister Kourtney Kardashian’s sons Mason and Reign turned 14 and 9 on December 14.

Khloe first shared a photo of Mason holding her daughter, True Thompson, 5, when she was a newborn baby.

“Happy birthday Mase,” she wrote on the photo, “How in the world are you 14 already?! True, Tatum, and I love you so much!”

The post was completed with two white heart emojis.

She also posted a photo alongside Mason where they both wore Christmas-themed onesies.

Khloe shared a throwback clip from Keeping Up With The Kardashians for her tribute to Reign.

He stood on top of a piece of furniture and asked Khloe: “Is this leather?”

Khloe laughed and said: “That is leather.”

“Happy birthday Reigny,” she captioned the post.

The final video that followed was of Reign and Mason hugging each other.

She wrote: “Brothers and best friends born on the very same day, I love you.”
