Red Velvet has a very special relationship with Knowing Bros., also known as Ask Us Anything. During the time the variety show was struggling to stay on air, the Kpop group's guesting for Episode 21 and Episode 84 really made the audience pay attention to the unique dynamic that the show presented and helped them become the top rating show that it is today.

The gang of Kang Ho Dong, Lee Soogeun, Kim Yong Cheol, Kim Hee Chul, Min Kyung Hoon, Seo Jang Hoon and Lee Sang Min like having Red Velvet members over so much that they ineract with the girls like family in all of their guestings, as a group or as individuals, reported Soompi.

This time around, Red Velvet's Joy will revisit the Knowing Bros. gang with two beautiful models - Jang Yoon Joo and Irene Kim, who will be headlining the latest season of Get It Beauty.

In the teaser clip for the episode, Jang Yoon Joo shows off her signature poses with a comedic twist, earning her praise from Jang Hoon. Irene also gets a chance to do some modelling amid teasing from the cast members as she seemed to get taller with each appearance.

However, Red Velvet's Joy, who could now be considered a Knowing Bros. ace, was welcomed with a lot of enthusiasm and teasing by the cast. Super Junior's Kim Heechul particularly poked some fun at her name, an English word which meant happiness. Heechul said that even if her name was Joy, she was always angry each time she appeared on the show.

"[Seo] Jang Hoon kept bothering me on that day. I'm sorry, Jang Hoon!" Joy said about Red Velvet's previous guesting on the show.

Red Velvet has been doing well in recent months, especially after the release of their comeback, The ReVe Festival which will be released in three chapters within the year. The ReVe Festival Day 1 dropped with the title track Zimzalabim this June while The ReVe Festival Day 2 was released in August. It is expected that the final installment will also be released in the last quarter of the year.

Red Velvet also maintained a strong showing in the brand reputation rankings for idol groups in August. The survey, conducted by Korean Business Research Institute through analyzing consumer participation, media coverage, interaction, and community awareness indexes of 100 idol groups, seeks to determine their effectiveness and popularity on a monthly basis, Soompi reported.

Red Velvet ranked in the third place, following Big Hit Entertainment's BTS and JYP Entertainment's TWICE.
