The quintuple threat Jennifer Lopez (actress/singer/dancer/designer/TV judge) upset two artists that she has collaborated with -- Enrique Iglesias and Pitbull -- when she won the 2011 American Music Award for Favorite Latin Music Artist.

"I didn't expect to win, hold on," Lopez said once she made it to the stage. But she wasn't flustered. She's J. Lo and she is always composed. La Lopez thanked God first and then went on to say, "It's been an amazing year in so many ways. It's been up and down, exciting and overwhelming, so many things."

Like a return to superstardom via 'American Idol' and a subsequent divorce from Marc Anthony? It has been quite a roller coaster year for J. Lo, but she always handles herself with grace and class, doesn't she? She always looks absolutely drop-dead gorgeous, too.

Lopez, wearing a one-sleeved, black lace dress with nude underlay and her hair slicked back into a tight bun, finished her speech, saying, "I want to thank my family most of all, my beautiful babies who inspire me to be a better person."

Congrats on the big win, J. Lo.
