Khloe Kardashian roasted her sister Kim Kardashian for arriving to her son Tatum’s second birthday party in a look worthy of an awards show on Sunday.

The 40-year-old Good American founder — who shares daughter True, six, and Tatum with Tristan Thompson, 33 — shared a video clip on Instagram of 43-year-old Kim making her arrival in a clinging gold gown.

‘Wowee, the Golden Globe is here, ladies and gentlemen!’ she said upon her billionaire sibling’s red carpet-ready entrance to the backyard soiree.

Kim interjected to defend her glitzy getup, stating that she had previously phoned her sister to ask if she should wear something ‘fancy’ or ‘workout clothes.’

The playful moment was shared with Kim’s six-year-old daughter Chicago, who clung to her glamorous mother’s hip throughout the snippet.

Kim looked typically stunning in the figure-hugging number, which gathered slightly at her trim waistline.

The floor-length frock boasted thin straps with a crisscross design at the center, which held a dark, round, stone medallion.

The SKIMS mogul put on a busty display in the ensemble, playing up her ample cleavage.

The fashionista punctuated the chic look with a pair of open-toe black heels.

She accented the dress with a small, square-shaped gold handbag.

Her raven-colored tresses were ironed bone straight and parted down the middle as they flowed down her back.

And she flaunted a full face of glowy matte makeup that complemented her smooth complexion.

Little Chicago, who Kim shares with ex-husband Kanye West, was clad in a sky blue T-shirt, jean shorts, and white Adidas Sambas.

Kim paid tribute to her nephew Tatum with a selection of photos shared to her Instagram Stories.

The mother-of-four uploaded a series of images from Chicago’s birthday party in January.

Several snapshots featured Kardashian in yellow patterned leggings and a black zip-up hoodie as she held Tatum on her hip.

On the bottom of one, she wrote in white font: ‘Happy 2nd Birthday Tatum. My baby!! I love you so so so much!’

Along with another photo of the aunt and nephew sharing an affectionate smooch, she wrote, ‘Auntie KiKi’s got you forever!!!’

Khloe reshared some of the posts to her Instagram Stories and added, ‘Tatum has the best aunties in the world.’

Along with a second repost, she said, ‘Tatum is so in love with you Auntie KiKi.’

Thompson had a dinosaur-themed ‘Two-a-saurus’ party that was attended by his various family members.

Khloe was a proud mom as she hosted the gathering in a white, eyelet, sleeveless and corseted mini dress that she teamed with big black sunglasses.

She enlisted party planner Mindy Weiss to transform the outdoor area of her $17M Hidden Hills mansion with life-size dino statues and palm-shaped pool floats.

Later on Sunday, Khloé shared a sweet post to Instagram to more formally celebrate Tatum’s birthday with her followers.

In one cute photo, he wore what looked like a dinosaur-covered pajama top while sitting on his beaming mother’s lap.

‘How are you two years old already?!’ she gushed in her lengthy caption. ‘The expression, “the days are long, but the years are short” could not be any truer. I feel like we have had a lifetime together yet You are only two years old.

‘I know we were destined to be together,’ she continued. ‘I know we have had many moments together before we ever met. The comfort I find in your eyes confirms we’ve known one another before.
