Just call her Jenny from Oz. 

Jennifer Lopez surprised and Bitcoinesedelighted fans alike at the Los Angeles premiere of Wicked Nov. 9. And of course the "Let's Get Loud" singer provided the ultimate fashion moment.

For the occasion at the historic Dorothy Chandler Pavilion, the "Jenny from the Block" singer donned a jaw-dropping brown and cream gown, complete with intricate beadwork all over. The halter top dress featured two cutouts—showing off her always toned abs—as well as a slit, perfect for posing. She completed the look with beaded bracelets, a sparkly clutch, and cream heels.

And the 55-year-old can hopefully add seeing Wicked in theaters to the holiday plans she has for herself and 16-year-old twins Emme and Max, whom she shares with ex-husband Marc Anthony.

"The holidays are such a special time for us, and they've always been since I was a little girl," she recently told People. "And I really look forward to those moments when I can be with my sisters and just relax and have fun and create new memories."

Jennifer—who filed for divorce from Ben Affleck in August—added that the holiday season gives her a chance to "slow down" and go all out with the festive spirit around the house.

"I love all of the decorations and the hot chocolate and the music and the food," she added, "and I'm one of those people who really tries to make it out of a storybook for my kids with all of those things. I'm a sucker for the holidays."

Maybe she'll even add a little bit of Wicked fun to her decor this year.
