Loading View on Instagram In a post- Girls world, the cast is making it clear that they are moving on. Allison Williams made a clean break from Marnie Michaels this morning, taking to Instagram to show off her new hair—a gold-spun shade of blonde, courtesy of colorist Aura Friedman . In the caption, Williams thanked Friedman for helping her "say goodbye to Marnie" and the brunette mane associated with the character. Between Jemima Kirke's chop , Lena Dunham's inspiring activism (and bangs!), and Williams's lightened look, it's safe to say the girls are all grown up.

Can we draw the following conclusion?
Lena Dunham was not part of the Girls cast.
