The lovely Katharine McPhee traded the American Idol stage for the fashion runway at Dina Bar-El's show on Tuesday during L.A. Fashion Week.

McPhee, 22, dazzled the crowd as she pranced down the catwalk with Bar-El at her side, while her rendition of "Somewhere Over the Rainbow" played in the background during the finale of the show.

The McPheever was clearly in top form after a tumultuous summer which saw her fracture her foot, suffer from bouts of bronchitis and laryngitis, and reveal she was once bulimic. Katharine glowed in a beige gown featuring a beaded halter empire waist and floating chiffon bottom.

McPhee and Bar-El have been friends ever since the designer created gowns for the budding popstar during American Idol. When not showcasing her inner supermodel, McPhee has been busy recording her debut album which is due out in November 28 -- right after Taylor Hicks' record debuts.

Here are Katharine McPhee pictures from the event. Note that her boyfriend, Nick Cokas, is visible in at least one of them. Good to see they're still on! Click to enlarge:
