'Newly engaged' Lady Gaga serves as bridesmaid at friend's wedding

Lady Gaga was recently served as a bridesmaid at her best friend's New Orleans wedding.

The 'Poker Face' singer posted a picture of her pink high heels that she wore on her friend's marriage and captioned it that watching best friend getting married, was one of the specialist times in her life, Us Magazine reported.

The 28-year-old singer wore a floor-length violet dress to the nuptials, but before the big day she posted some other pictures with her gal-pals one in a black dress, and one in hat while having brunch with the bride.
