Jessica Simpson: Supportive Big Sister!

Jessica Simpson shows some sisterly love by attending younger sister Ashlee Simpson‘s performance as Roxie Hartin Chicago on Thursday (January 7) in New York City.

Jess, 29, saw the performance with her mom and a few family friends. Ash was even nice enough to sign autographs and take pictures with fans after the performance!

Former Destiny’s Child singer Michelle Williams will take over for Ashlee starting early next month.
