AMAs 2013: Katy Perry Brings Big Book, Lady GaGa Brings Horse on Red Carpet

Perry, the opening act of the music awards show, carried a yellow clutch resembling a big book while GaGa rocked the red carpet on top of a white horse.

Katy Perry was one of the first music stars to walk on the red carpet of American Music Awards on Sunday, November 24. The "Roar" singer wore a flowing black gown from Oscar de la Renta and made a statement with her yellow big book clutch and a big floral ring. She was scheduled to open the show with "Unconditionally".

The girls of "Glee" showed major cleavage with their ensemble. Jenna Ushkowitz wore a sleeveless orange gown with plunging neckline while Naya Rivera stunned in a black Michael Kors dress with long tail, Jimmy Choo shoes and vintage YSL gold cuff clutch.

Another highlight from the red carpet is the appearance of Kelly Clarkson who debuted her baby bump for the first time since announcing the pregnancy last week on Twitter. She walked the red carpet with husband Brandon Blackstock. Actress Emma Roberts chose silver Lanvin's Ete 2014 Women's Collection by Alber Elbaz and paired it with satin maroon clutch.

In a rather shocking appearance, Ke$ha showed off her slim legs in an elegant black dress with ruffles on the hip. With her cotton candy colored hair let loose and minimal jewelries, the "Tik Tok" singer almost looked like Lady GaGa. Speaking of which, the "Applause" crooner was head to toe Versace, the fashion house in which she is a spokesperson. However, the eye catcher was the white horse she rode on, the one that complimented her all-purple ensemble. She will perform her single "Do What U Want" with R. Kelly.

Meanwhile, Taylor Swift was leggy in a gold strapless Julien Macdonald dress and Jimmy Choo shoes. She completed her look with Lorraine Schwartz jewels and a Tod's clutch. Miley Cyrus, who has just turned 21, ditched dress for a white Versus Versace suit that bared her cleavage. She topped off the masculine look with Saint Laurent shoes and Lorraine Schwartz jewels. Cyrus is scheduled to perform "Wrecking Ball".

2013 American Music Awards is broadcast live from Nokia Theatre L.A.
