The two artists first teased a possible collab in March, sharing a photo of themselves in the studio.

"Can’t wait to finish our song ? compartir contigo en el estudio o verte ayer actuar me inspira sooo much, love you B," Rosalía wrote on Twitter, which got fans hyped up.

2019 has been an amazing year for the "Malamente" singer, who is nominated for five awards. "I feel so grateful. So happy."

Rosalía is also set to take the stage at the 20th annual celebration."It's a moment to celebrate music in Spanish, in many different ways because every artist has a different point of view and I think a lot of artists are celebrating their roots and that’s amazing," she said of the night. "And I feel very grateful that I can perform with my songs and tonight is going to be very special."

This week, ET also caught up with Ricky Martin, who is hosting the awards show, where he teased what fans can expect from the 20th-anniversary celebration.
