MAMAMOO made their long-awaited comeback as a group on October 11 with the mini album Mic On to the delight of their fans, adorably called the moomoos.

Among Mamamoo fans are some famous fans, as Red Velvet's Seulgi posted a screenshot of her listening to "Illella," the title track from the Mic On album. The caption of Seulgi's post read, "MAMAMOO did it!!"

The screenshot shows Seulgi had favorited the song on Melon.

Seulgi recently made her solo debut with 28 Reasons, and MAMAMOO member Moonbyul also showed her support for Seulgi's music through her Instagram Story.

Seulgi reposted the story with a caption saying that she was looking forward to MAMAMOO's group comeback and wanted to see Moonbyul again!

Seulgi and Moonbuyl collaborated on the track 'Selfish' in 2018. And since then, they have remained friends.

Their friendship hasn't known since faded since Seulgi had invited MoonBuyl on his show SEULGI.zip and the fans had been able to see that they shared real friendly chemistry.

Fans loved this great friendship between the two artists. MAMAMOO and Seulgi will be promoting during the same period with their respective titles; fans assume there will be on-screen interactions.

In the meantime, please enjoy Mamamoo and Seulgi's comeback title.
