Jessica Simpson Shows Off Her Legs -- But It's Not Working!

Jessica Simpson walks alongside her father and manager Joe Simpson, after attending her sister Ashlee‘s second performance of Chicago on Broadway on Tuesday (December 1).

At Monday’s after-party for lil sis Ashlee‘s debut in Chicago The Musical, Jessica had fun socializing with Ashlee‘s Broadway co-stars. She joked that there were only two straight men in the private party room and playfully tried to strike a pose and show off her legs to the men around her.

“It’s not working!!!” she laughed.

FYI: Jess is wearing J Brand “901″ denim leggings.
