If you had a close friend who was a celebrity, would you still ask them to be in your wedding? Lady Gaga was a bridesmaid in her best friend's wedding, and did NOT upstage the bride! She looked gorgeous in the same light pink dress as the other girls, and a pretty flower in her hair.
Guests might not have even guessed it was her! Click HERE to see the picture.
MY best friend just got married too! Friends since 2nd grade <3 (NOT 1st though, when we both chased after the same boy on the playground!)
