Ashley Simpson-Wentz made her Broadway debut last night and ever-supportive sister Jess said her younger sibling gave a stand-up performance.
"I'm always so proud of my sister," Jessica Simpson gushed to OK! magazine through tears. "I think she frickin' nailed it!"
Jessica showed up at New York's Ambassador Theater in a silver-scaled sequined gown to cheer on Ashley, who played Roxie Hart and appeared on stage with dark hair, pale skin and a svelte figure.
The 25-year old is married to Fall Out Boy bassist Pete Wentz, who was also at the show.
"Roxie was all Heart! Watching her up on that grandiose stage made me the proudest sister in the world. I love ya honey, I love ya!" Jess wrote on her Twitter page after the show.
The protective older sister took "Melrose Place" to task after the TV series dropped Ashlee from the lineup.
