Latto Thrilled Song with Jung Kook is Fastest to 1 Billion Spotify Streams

Latto has a whole lot to celebrate after her track with Jung Kook broke a record for fastest to reach a billion streams on Spotify ... and she told us why she's HYPED about the big news.

We got Latto Wednesday at LAX and congratulated her on the huge accomplishment for "Seven" ... and the one word she used to sum up her reaction to it is "crazy."

Latto says the track's record-breaking success has made her really grateful. She choked up as she told us about recently losing a dear friend, and said she feels this Spotify record is a sign her late pal still has her back from the afterlife.

In terms of what's next, Latto is more than ready to collab with the BTS member on another hit -- saying she's even got something in the works that'd be perfect for Jung Kook.

She also gives a shoutout to his army of fans -- in the U.S. and abroad -- telling us they've been showing her nothing but love and support, and she's all for making them happy again.
