Selena Gomez

Selena Gomez is the hostess with the mostess in a glamorous champagne-coloured mini dress and amazing purple peep-toe heels. The singer, who just recently left a hospital due to exhaustion, looks more mature than her 18 years in the dress with its shredded layers. We wish she would have posed with her boyfriend Justin Bieber. (George Pimentel/WireImage.com)
