Watch Christina Aguilera & Kelly Clarkson on Sunday Night's Academy of Country Music Awards

Courtesy ABCIt’s called the Academy of Country Music Awards, but this Sunday night’s 50th anniversary installment of the ACM telecast will include some of pop’s biggest stars.

Kelly Clarkson will present an award at the show — not surprising, since her stepmother-in-law Reba McEntire is one of the performers, and her husband Brandon Blackstock manages another one of the performers, Blake Shelton

Meanwhile, Christina Aguilera, currently part of a multi-episode story arc on ABC’s Nashville, will perform one of her Nashville songs, “Shotgun,” on the telecast, and also duet with country stars Rascal Flatts on their song “Riot.”  In addition, former boy bander-turned-solo pop star Nick Jonas will be performing with country duo Dan + Shay.

Other stars taking part in the awards telecast include American Idol judge Keith Urban, former American Idol judge and Aerosmith frontman Steven Tyler, Sofia Vergara, Reese Witherspoon, Beth Behrs, Lady Antebellum, Florida Georgia Line and Garth Brooks.  The show airs Sunday night on CBS starting at 8 p.m. ET, live from AT&T Stadium in Arlington, Texas.
