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.

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.
