Selena Gomez took a different tack fashion-wise at the Alliance For Children's Rights dinner, a charity event in Beverly Hills, Calif. on Thursday, as she took to the red carpet in a black dress that draped to the floor.

The Monte Carlo beauty, 20, went light on the make-up and paired her long dress with a silk blouse. She took to Twitter Thursday to thank her fans, writing, "I can't thank you enough :) love you all so much!!"
