The red carpet was on fire Thursday night, as stars were out in about all over the world, dressed in the best and worst fashions. RadarOnline.com has

all the photos in our daily photo feature!

At the Madrid premiere of Burlesque, Christina Aguilera hit the high note in flapper fantastic fashion! The soon-to-be divorcee sizzled in a body-skimming beaded Marchesa number from the Resort 2011, which she perfectly paired with YSL Tribtoo heels and a splash of her trademark red lipstick.

Cher, on the other hand, experienced the ultimate fashion disaster! The superstar icon must have forgotten to put her contact lenses in, hitting the

red carpet wearing a completely see through bra with a sheer shirt, exposing herself to the crowd of sophisticated Spaniards! At least Kristen Bell was on hand to balance things out, looking stunning in an embellished neck Alberta Ferretti mini.

At the Miss Golden Globes bash in Los Angeles, Lucy Hale was a Pretty Little Liar in a corseted Foley + Corinna number and bright red pumps, while Ashley Tisdale looked lovely in lace, wearing a Backstage dress with oodles of Planet Blue jewels.

Nicki Minaj resurrected Britney Spears' Toxic nude bodysuit to celebrate her 26th birthday in Sin City, looking totally wacky per usual.

Julianne Moore was feathered and fabulous in Paris, wearing Lanvin to the Bvlgari 125th Anniversary. Cameron Diaz was also in the city of lights,

looking utterly classy and sophisticated in a gorgeous coat and trousers.
