Celebrity Bridesmaids: Katherine McPhee Acts As Maid Of Honor At Sister's Nuptials

"Smash" actress Katharine McPhee may be used to being in the spotlight, but she was careful not to outshine her older sister, Adriana, who recently got married in Los Angeles.

The 28-year-old actress and singer acted as maid of honor at her sister's wedding, donning a pale pink bridesmaid gown and a simple updo for the occasion. The Daily Mail recently released photos of the happy bridesmaid and the glowing bride.

McPhee made it clear that she was excited for her sister to the knot, tweeting: "Hope everyone had a gr8 long weekend! I am off to LA tomorrow for many things. One being my Sisters wedding!!"

McPhee has been married to producer Nick Cokas since 2008.

But she's not the first celebrity to be part of a wedding party -- in fact, several other famous faces have played a part at their loved ones' nuptials.
