Beyoncé's daughters Blue Ivy, Rumi sport latest collection in Ivy Park ad: Watch

Beyoncé’s daughters Blue Ivy and Rumi are making fashionable cameos in the singer’s campaign for her latest Ivy Park collection, proving that style is truly a family affair.

The two made an appearance in a promotional video for Halls of Ivy, under Beyoncé’s activewear line's collaboration with Adidas. Beyoncé posted the video to her Instagram on Tuesday, which also featured appearances from celebrity children Natalia Bryant, daughter of the late Kobe Bryant, and Ava and Deacon Phillippe, daughter and son of Reese Witherspoon.

In one clip from the ad, Blue Ivy, 9, and Rumi, 4, can be seen in matching houndstooth-printed outfits alongside Beyoncé.

The new collection features “classic fashion silhouettes, infused with individual style, swagger and the spirit of following your wildest dreams,” according to the Adidas website.

Blue Ivy and Rumi's campaign appearance electrified social media.

"BLUE AND RUMI TAKING OVER YUPPPP," @johnvenchy commented on Instagram.

User @44beystreet added: "Rumi looks so beautiful! Omg!!! 😍😍"

Instagram user @jj._jordan was genuinely stunned by the girls' growth, commenting, "Blue and Rumi are getting so big😭❤️👑"

Halls of Ivy marks the fifth joint collaboration between the brands, according to the Adidas website. The kidswear aspect of the collection will include “34 apparel styles,” ranging from a faux fur coat and houndstooth cotton twill jacket, to a cropped tee and houndstooth bra, the website states.

This isn’t the first time Blue Ivy and Rumi have struck a pose or two for the camera. In August, Blue and Rumi, along with Rumi’s twin brother Sir, modeled looks from Ivy Park’s rodeo-inspired children’s collection, including cow-print leggings and a blue cowboy hat.

"My kids are usually on set with me for shoots, and we’d find ourselves putting them in extra-extra-smalls so we could match," Beyoncé said in an interview with Harper’s Bazaar in September. "So, it is a natural progression for Ivy Park to introduce a selection of key silhouettes in children’s sizing."

Halls of Ivy will be available exclusively on the Adidas website Dec. 9, after which the collection will be launched globally Dec. 10, according to the Adidas website.
