The 61st Grammy Awards will take place at the Staples Centre in Los Angeles.
Big Hit Entertainment has yet to confirm the reports of BTS's appearance.
While it's not yet clear which award they will present, the band is also nominated for their own prize.
A source reportedly revealed Suga, J-Hope, Rap Monster, Jin, Jimin, V and Jungkook would present an award during the live show. The art director of "Love Yourself: Tear" is HuskyFox.
BTS, which has seen huge global success in recent years, charmed tens of thousands of Singapore fans last month during their sold-out show at the National Stadium. It marks the first time a K-Pop album made the cut for any category from the prestigious award-giving body. Make sure to tune in to the "2019 Grammy Awards" this weekend! The performers for the night include Camila Cabello, Cardi B, Brandi Carlile, Miley Cyrus, Dan + Shay, H.E.R., Post Malone with the Red Hot Chili Peppers, Shawn Mendes, Janelle Monáe, and Kacey Musgraves.
Maroon 5 was only nominated for Best Pop Duo/Group Performance for "Girls Like You" with Cardi B. Their absence at the Grammys is expected, since the show is scheduled for only a week after their Super Bowl LIII halftime show performance.
The rap superstar Kendrick Lamar leads the Grammys with eight nominations.
The 2019 Grammy Awards will air on Sunday, February 10, at 8 p.m. on CBS.
