She is used to being the star of the show, but it was Katherine McPhee's older sister Adriana who took center stage on Saturday for her wedding day.
The Smash star and former American Idol contestant played her supporting role of matron of honor to perfection as she floated through the Los Angeles nuptials in an ethereal pale pink Grecian gown with her long hair pulled loosely back in an up do.
Dressed in a beautiful puffy white gown and floating veil, the bride made sure all eyes were firmly on her and there was no risk of a "Pippa Middleton style attention takeover" by her little sis like at the royal wedding last year!
McPhee was joined by her husband, Nick Cokas, who she married in 2008, while a perfect little blonde haired flower girl shared in the fun too.
The 28-year-old actress star had been open about her struggle with an eating disorder earlier in her career, but when she raised her arms in joy after the ceremony her flexed biceps left no doubt that she is currently in great shape.
The family has been getting ready for Adriana's big day for weeks. "I am off to LA tomorrow for many things. One being my Sister’s wedding!!” Katharine tweeted last month.
