Jessica Simpson Really Loves 'All That Jazz'

Jessica Simpson is certainly a supportive sister. But she must be a big fan of Broadway's "Razzle Dazzle" as well: Simpson has stepped out to see sister Ashlee in Chicago no less than five times in a month!

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"
