Dragon Dressing

The stars were in 3D at the Los Angeles premiere of How to Train Your Dragon on Sunday afternoon, dressed in Springy and fun fashion. Ugly Betty star America Ferrera charmed up a black pantsuit by adding a snaky belt, while Gerard Butler looked haute and hunky in a grey suit.

Bella Thorn and Ariel Winter looked playful in bold colors and patterns, while Terri Seymour went for a minimal, but sexy look, wearing a dark, baby doll mini.
