Ashlee Simpson-Wentz makes her broadway debut

Moving right along from her failed attempt on “Melrose Place,” Ashlee Simpson made a triumphant debut on Broadway last night in “Chicago.”

The “Pieces of Me” songstress looked lovely as she played the role of Roxie at the Ambassador Theatre, with husband Pete Wentz and parents Tina and Joe Simpson in the audience.

Also in the house was sister Jessica Simpson, who was reportedly quite nervous for her little sis. An eyewitness told press, “She kept turning to her mom and saying she had butterflies. It was very cute. She must have said it five times after she took her seat.”

And Jess was reportedly quiet pleased with Ashlee’s performance. “I love that she’s her own Roxie — she’s done it her own way. I’m always so proud of my sister. I think she frickin’ nailed it!”

Ashlee Simpson couldn’t hide her sense of pride after performing Chicago at the Ambassador Theatre in New York City on Monday night (November 30).

Looking waif-like and pale, the young starlet received applause and accolades following her portrayal of wannabe Jazz singer Roxie Hart.

Ashlee had the support of her family in the audience, including hubby Pete Wentz, father Joe Simpson and sister Jessica Simpson, who sparkled in sequins.

Before the performance, Jessica tweeted: “I’ve looked forward to this moment since I watched her own the stage in London.”

After the show, she added: “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! Grrrrrr!”

After the show, Ashlee ditched the costume, threw on her best pearls and joined her friends, family and crew for an afterparty at Inc. Lounge.

Ashlee will play Roxie in the Tony Award-winning musical for a 10-week limited engagement, through February 7, 2010
