  • The American Music Awards will be broadcast starting at 8 p.m. ET Sunday
  • Macklemore & Lewis have the most nominations with six
  • Katy Perry will open the show, and Miley Cyrus will close it

(CNN) -- There may be some shockers Sunday night at the 2013 American Music Awards.

Katy Perry is scheduled to open the AMAs with a performance while the always-unpredictable Miley Cyrus will close out what is called "the biggest party on television."

In between, a cadre of musical stars will take to the stage, including Lady Gaga, Justin Timberlake, Taylor Swift, Lady Gaga, Rihanna, One Direction, Ariana Grande and Florida Georgia Line.

So far, the only promised surprise is female R & B group TLC, who have said they will be joined on stage by a special guest. Speculation over who that could be has spun from a hologram of the late Lisa "Left Eye" Lopes to a possible new member of the group.

Fans voted online and Twitter to select the winners. This year, rap duo Macklemore & Lewis have snagged the most nominations with six, including new artist of the year, artist of the year and single of the year for their hit song "Thrift Shop." Swift and Timberlake each have five nominations while Rihanna, Robin Thicke and Florida Georgia Line have four nominations apiece.

Rapper Pitbull hosts this year awards show, his first hosting gig. He is also set to perform his new single, "Timber," with pop star Ke$ha.

"I hope you got that delay button ready; we're going to have a lot of fun," he told ABC.

The American Music Awards will be televised live on ABC at 8 p.. ET from Nokia Theatre in Los Angeles.

Sunday night's red carpet festivities included performances by singer Jesse McCartney and girl group Fifth Harmony.
