AMAs Backstage: Rihanna on her 'R-Rated' Outfit; Jennifer Lopez on her 'Planned' Fall



The "2009 American Music Awards" was jam-packed with performances from a large spectrum of genres. Janet Jackson kicked off Sunday night's festivities in Los Angeles. Entertainers such as Adam Lambert, Jennifer Lopez, Rihanna, Lady Gaga, Shakira, and Whitney Houston followed with elaborate production numbers. ET's Kevin Frazier spoke to some of the artists after their show-stopping routines.

J-Lo got ready to rumble with a boxing theme for her single "Louboutins." She said, "It's kind of metaphoric, coming back into the ring."

She also jokes that she "planned" the fall she took during her choreographed dance: "You know how sometimes a champ, like late in the ring, you fall down, you get right back up. That's the mark of a champion right there."

Rihanna made a statement in her ensemble, calling it "armed and dangerous, buy sexy." She told Kevin what it felt like to perform "Wait Your Turn" in front of the energized audience: "When the curtain came up and I saw everyone on their feet...I almost couldn't sing. I was so overwhelmed." Her new album, "Rated R" is in stores now.
