The "Queen" rapper tweeted out "Uh!!! What’s Good KOREA?!" tagging the song name and the highly popular group on Friday.
This version of “Idol” is featured on BTS' repackaging of "Love Yourself: Answer," which came out today.
BTS released a snippet of the song earlier this week and when one fan ran it through Shazam on Thursday, the result showed Nicki's name as a featured artist. Fans went nuts about the idea of a possible collaboration, but hours later, her name mysteriously disappeared.
It didn't seem to bother Nicki though.
While she didn't confirm the rumors until now, she didn't do much to downplay them either, liking several collaboration-related tweets from fans.
