Los Angeles, California - Kim Kardashian's little ones are not so little anymore, as the reality star's Christmas snaps prove!

The 44-year-old took to Instagram on Sunday to share a few photos from the famous family's low-key Christmas Eve party, which boasted a much smaller guest list than in years past.

In the photos, Kim posed alongside her four kids – North (11), Saint (8), Chicago (6), and Psalm (5) – all of whom she shares with ex Kanye West.

Kim sported another red-hot holiday look in a red satin gown, with daughter Chicago matching her mom in a red leather t-shirt dress with coordinating cowboy boots.

The eldest of the bunch opted for a suit-inspired ensemble featuring a white corset-style top with a black necktie, along with a cropped black blazer, black miniskirt, and black boots.

As for the boys, both Saint and Psalm went for a more casual style with similarly styled jackets paired with dark shirts and pants.

"Absolute perfection," Khloé Kardashian commented under the post.

Though the annual Christmas Eve bash was limited to close family this year, Khloé wasn't able to attend, as her daughter, True, came down with a nasty fever.

Younger sisters Kendall and Kylie Jenner, meanwhile, showed off their respective 'fits in some viral social media posts, revealing that both wowed in winter white looks at Tuesday's party.
