Girls have to stick together! On Saturday, June 28, Lena Dunham stepped out of the spotlight to serve as a bridesmaid in a pal's wedding. Though she didn't name the friend, Dunham posted several photos in a floor-length grey dress with capped sleeves. 

"Getting ready for my best friend's wedding," the Girls creator tweeted. "Potent, emotional, feel someone should make a movie about it. Called 'Wedding Of My Best Friend.'"

She posed with the other two bridesmaids, showing off the cutout back of the dress. 

"Sisters of the cloth," she captioned one image.

She also Instagrammed a picture of the bride's tulle-covered gown, writing, "It waits for her #bride #inthesewoods."
