Jessica first attended the show on Nov. 30, which was Ashlee's Broadway debut, at the Ambassador Theatre in New York City. "Roxie was all Heart!" Jessica tweeted of her sister's performance as Roxie Hart. "Watching her up on that grandiose stage made me the proudest sister in the world. I love ya honey, I love ya!. Grrrrrrr"
The next night, Dec. 1, Jessica was back again, tweeting this time: "Night #2 :) I'm so proud!! Butterflies all over again!!!" And after taking a night off, it seems Jessica went through withdrawal because she returned to see Chicago on Dec. 3 and Dec. 4.
And on Dec. 23, she was back!
The first time, however, that Simpson saw her sister in Chicago was on Sept. 25, 2006, when Ashlee appeared in a West End production of the show in London.
